Table 1 H-<strong>SAF</strong> products list<br />
2.2 General requirements<br />
UR.GE.01 - H-<strong>SAF</strong> shall generate and disseminate satellite-derived products according to<br />
the detailed product requirements presented in section 3.<br />
UR.GE.04 - The H-<strong>SAF</strong> products shall cover as a minimum all EUMETSAT member and<br />
cooperating States and associated costal zones. The nominal H-<strong>SAF</strong> area coverage<br />
stretches from latitude 25°N to 75°N, longitude 25°W to 45°E.<br />
UR.GE.05 - The distributed H-<strong>SAF</strong> products shall be associated with characterisation of<br />
their error structure so that users will be guided to appropriate utilisation. Guidance to<br />
utilisation will also be supported by education and training activities on the nature of the<br />
products and their applicability in hydrology and water management.<br />
UR.GE.06 - All products generated in H-<strong>SAF</strong> shall be collected in near-real-time in the<br />
central archive (real or virtual), and shall be made available to the user community through<br />
the EUMETSAT Data Centre.<br />
UR.GE.13 - In order to enable reconstruction of time series, or re-calibration and/or reprocessing<br />
by advanced algorithms, raw data shall be archived at the acquisition sites<br />
(either physically or virtually) and made accessible to the H-<strong>SAF</strong> central archive.<br />
UR.GE.14 - The system shall be designed to deal with emergency management such as<br />
recovering missed real time production. The options range from the generation of products<br />
at the closest possible time (though delayed), to highly-delayed recovery only for the<br />
purpose of reconstructing time series, to acceptance of a definitive gap if the recovery is<br />
impossible or not sufficiently cost-effective.<br />
UR.GE.15 - The H-<strong>SAF</strong> shall install and maintain a H-<strong>SAF</strong> web site and maintain a help<br />
desk. The web site will provide general public information on H-<strong>SAF</strong>, H-<strong>SAF</strong> products<br />
description, rolling information on the H-<strong>SAF</strong> implementation status, the publication of<br />
product images, and all related documentation.<br />
UR.GE.DOC.1 - The H-<strong>SAF</strong> shall make available updated user documentation related to<br />
its (pre-) operational products: ATBD, <strong>Product</strong> User Manual and Validation Reports.<br />

3.1 Precipitation products requirements<br />
3.1.1 Precipitation Accuracy Values<br />
<strong>Product</strong> requirements for accuracy are adopted on the basis of the principle that values be<br />
unified for each sub type of product family and by making use of the following criteria for<br />
the three values:

OPTIMAL: About intensity precipitation products, the impact of the statistic<br />
characteristics of the parameter/phenomena onto the best available observations<br />
(raingauges) was referred as from the WMO report on “field intercomparison of rainfall<br />
intensity gauges”. That report shows that rain-gauges adopting the time sampling of 1<br />
minute give a percentage error from the reference raingauge of about 30% and only<br />
with specific laboratory tuning of the instruments it is possible to achieve the 5% error.<br />
These results are related to rainfall intensity of about 12mm/hr as inferred by the<br />
observation of mechanical raingauges (the greatest majority of the operational<br />
instruments).<br />
Considering what above the optimal accuracy requirements for precipitation intensity has<br />
been revised as following:<br />

Instantaneous precipitation maps generated from MW images taken by cross-track scanners<br />
on operational satellites in sun-synchronous orbits processed soon after each satellite pass.<br />
Before undertaking retrieval the AMSU-A resolution is enhanced by blending with AMSU-<br />
B/MHS.<br />
The retrieval algorithm is based on a neural network trained by means of a pre-computed<br />
cloud-radiation database built from meteorological situations simulated by a cloud resolving<br />
model followed by a radiative transfer model<br />

Generation frequency<br />
Precipitation rate from cross-track scanning instruments will be derived from AMSU-A and<br />
MHS radiometers onboard NOAA and Metop operational satellites. Nevertheless, PR-OBS-2<br />
will keep exploiting AMSU-A/B (on NOAA-15 & -16) measurements until available<br />
Up to six passes/day with somewhat irregular distribution across the day.<br />

Instantaneous precipitation maps generated by PMW satellite sensors from operational<br />
satellites in sun-synchronous orbits, time-interpolated by exploiting the dynamical information<br />
observed on IR images from GEO.<br />
The algorithm performs the interpolation soon after the acquisition of a new image from LEO.<br />
This method (“Morphing”) is particularly suited for computing accumulated precipitation of use<br />
in hydrology.<br />
Comments<br />
See the comments about the product retrieved by SEVIRI.<br />
We are assuming that the commissioning phase of MTG will start at the end of CDOP-2,<br />
however the prototype of product can be designed on the requirement of MTG service and<br />
simulated data can be used. If the simulated data or a simulator will be available, the H-<strong>SAF</strong><br />
will produce a data set based on simulated data and the product will be tested.<br />

3.2 Soil Moisture products<br />
3.2.1 Soil Moisture Accuracy Values<br />
During Development Phase and CDOP1, Accuracy <strong>Requirement</strong>s for products H14 SM-<br />
DAS-2 and H08 SM-OBS-2 have been given in volumetric unit (m3m-3) and the main<br />
score to be evaluated was the Root Mean Square Difference, supportive scores being: the<br />
Mean Error (or bias, ME), the Standard Deviation (SD) and the Correlation Coefficient<br />
(CC).<br />
The first definition of H-<strong>SAF</strong> soil moisture validation goals stems to a large extent from the<br />
efforts to build the SMOS and SMAP satellites that both aim to retrieve the absolute<br />
volumetric soil moisture content with an RMSD of 0.04 m3m-3. But considering the<br />
evolution of the literature on this topic over the last few years one can clearly see a shift in<br />
the way of how the validation of remotely sensed / modelled soil moisture data is being<br />
regarded. RMSD by itself is not sufficient, other measures such as CC are also important,<br />
and for some applications even more important than the RMSD (Entekhabi et al., 2010;<br />
Brocca et al., 2011).<br />
Several authors have demonstrated that local measurements could be used to validate<br />
model output as well as remotely-sensed soil moisture (SM) at a different scale (e.g.<br />
Albergel et al, 2009, 2010; Rüdiger et al., 2009; Brocca et al., 2010a; 2011). However,<br />
spatial variability of SM is very high and can vary from centimetres to metres. Precipitation,<br />
evapotranspiration, soil texture, topography, vegetation and land use could either enhance<br />
or reduce the spatial variability of soil moisture depending on how it is distributed and<br />
combined with other factors (Famiglietti et al., 2008; Brocca et al., 2010b, 2012).<br />
Differences in soil properties could imply important variations in the mean and variance of<br />
soil moisture, even over small distances. Each soil moisture data set is characterized by its<br />
specific mean value, variability and dynamical range. Saleem and Salvucci (2002) and<br />
Koster et al. (2009, 2011) suggested that the true information content of modelled soil<br />
moisture does not necessarily rely on their absolute magnitudes but instead on their time<br />
variation. The latter represents the time-integrated impacts of antecedent meteorological<br />
forcing on the hydrological state of the soil system within the model.<br />
The high spatial variability of in situ SM used for validation as well as SM data set specific<br />
characteristics suggest that the Correlation Coefficient (CC) should be the main score to<br />
be evaluated. On this basis the soil moisture products development and validation groups<br />
propose to change the main score to evaluate the "<strong>Product</strong> <strong>Requirement</strong>s" for H08 and<br />
H14 products from the RMSD to the CC. The following values are proposed as accuracy<br />
thresholds:<br />
• Threshold accuracy: 0.50<br />
• Target accuracy 0.65

• Optimal accuracy 0.80<br />

of at least 12 months are needed).<br />

Re-analysed liquid soil moisture profile index for four different soil layers (covering the<br />
root zone from the surface to ~ 3 metres) generated by the ECMWF land surface reanalysis<br />
system at 24 hour time steps. H-27 provides a consistent time series of both<br />
surface and root zone soil moisture with a daily global coverage which is highly relevant<br />
for hydrological applications and water budget investigations.<br />
The analysed soil moisture fields are based on a modelled first guess, the screen-level<br />
temperature and humidity analyses, and the ASCAT-derived surface soil moisture. They<br />
are then re-scaled to soil wetness index by normalising by the saturated soil moisture<br />
value as a function of soil type.<br />
The Global product is generated using the re-analysed Global surface soil moisture<br />
product assimilated in the ECMWF land surface re-analysis suite. This product will be<br />
developed in CDOP-2 based on CDOP developments. . Data assimilation is indeed the<br />
only approach that enables to retrieve both surface and root zone soil moisture from<br />
satellite surface swath data.<br />

3.3 Snow products<br />
3.3.1 Snow Accuracy Values<br />
<strong>Product</strong> requirements for accuracy were adopted taking in consideration the actual<br />
performances achievable as demonstrated by continuous validation and taking in<br />
consideration the baseline proposed requirement values have not been tested before.<br />
Especially in the mountainous areas, 5 km x 5 km spatial resolution of the product can not<br />
be represented by the distribution of the available ground data. During the validation<br />
analysis simple satellite-ground comparison is performed. When automatic snow<br />
observation stations (specially established at most proper sites for snow measurement in<br />
Turkey) which are used in the comparison at high altitudes (elevation >2000 m) 90% POD<br />
values are obtained. However between 750 m and 2000m due to morphology of snow<br />
changes rapidly and the distribution of the ground observations are synoptic, the results<br />
are decreasing due to the available limitations.<br />
In Remote Sensing Community the question of the acceptable level of accuracy is often<br />
answered by reference to the seminal work of Anderson et al. (1976) who outline the<br />
criteria for an effective land use and land cover classification scheme for use in<br />
conjunction with remotely sensed data. Specifically, Anderson et al. (1976, p. 5), citing the<br />
earlier work of Anderson (1971), state that “the minimum level of interpretation accuracy in<br />
the identification of land use and land cover categories from remote sensor data should be<br />
at least 85 percent”. Therefore, although an 85% accuracy target is widely accepted by the<br />
remote sensing community as a benchmark, as several recent examples indicate (Foody<br />
2002, Reese et al. 2002, Fuller et al. 2003, Tømmervik et al. 2003), its usefulness as a<br />
standard is unclear. Others have also questioned the validity of the 85% target (Laba et al.<br />
2002, p. 453). The accuracy assessments of several recently completed regional-scale<br />
land cover mapping projects indicate that producer's and user's accuracies are stabilizing<br />
in the50-70% range, independent of level of taxonomic detail or methodological<br />
approaches (Edwards et al. 1998, Ma et al. 2001, Zhu et al. 2000). Additional<br />
improvements in accuracy are not likely, and that only through the use of sensors with high<br />
spectral, spatial, and temporal resolution will map accuracies approach 80%.<br />
The appropriate accuracy assessment protocol often develops from consideration of the<br />
following question: Is the product sufficiently accurate for a specific application? The<br />
understanding is that not all applications require the same level of accuracy to be<br />
successfully accomplished, and therefore the same level of effort need not be expended to<br />
determine product accuracy for different possible applications. For hydrological<br />
applications 85% POD and 15% FAR would be ideal in using the snow cover maps for<br />
runoff generation.<br />
Furthermore, different threshold requirements for flat/forested areas and mountainous<br />
areas should be identified. Revised threshold values are 0.8 POD for flat and forested<br />
areas and 0.6 POD for mountainous areas. For the target values, the proposed<br />
requirement is 0.85 POD for the flat and forested areas, and 0.7 for the mountainous area.<br />
Regarding the FAR, the threshold is 0.2 for flat area and 0.3 for mountainous area, and for<br />
the target value: for 0.15 for flat area and 0.2 for mountainous area.

The “deficit” of brightness in respect of the maximum one is correlated to the lack of snow in the<br />
product resolution element. In the case of forests, the signal attenuation due to forest canopy<br />
obstruction is taken in to account by application of transmissivity map assembled in advance using<br />
MODIS and GlobCover land cover data.<br />
In order to search for cloud-free pixels, multi-temporal analysis is performed over all images<br />
available in 24 hours (in daylight)<br />
Comments<br />

Maps of snow water equivalent derived from MW measurements sensitive to snow thickness and<br />
density.<br />
The product may be processed in different ways and have different quality depending on the<br />
surface being flat, forested or mountainous.<br />
The algorithm is based on assimilating MW brightness temperatures of several channels at<br />
frequencies with different penetration in snow, into a first-guess field built by the (sparse) network<br />
of stations measuring snow depth for flat areas, for mountainous areas snow depth measured at<br />
stations is not used directly in the algorithm<br />
