Objectives and tasks:
In this workpackage ECMWF will investigate the use of a new snow analysis scheme based on an Extended
Kalman Filter (EKF) approach in order to use satellite snow data in the SM-DAS-2 production chain. This
constitutes a major development which is being performed in both the research branch of the ECMWF
Integrated Forecasting System and in the H14 production chain based on the ECMWF Land Surface Analysis
System. These developments started in CDOP and will be continued in CDOP-2. Improving the snow analysis
scheme is of crucial importance to improve the accuracy of the retrieved root zone soil moisture product in
regions covered by snow in winter time. This is expected to be highly valuable in during the melting period in
particular. The system will be tested to use H-SAF snow data in the early stage of the CDOP-2 and it will be
implemented in the H14 production chain in case it has a positive impact on both soil moisture and lower
level atmospheric variables.
In parallel, improvements in the land surface model H-TESSEL, used in the data assimilation scheme will be
investigated. Improving the land surface model soil moisture vertical representation might have a great
impact on the root zone soil moisture profile quality. This will be investigated through the visiting scientist
programme (3 months in CDOP-2).
Based on the Visiting Scientist programme (3 months) the quality of the precipitation used in the data
assimilation suite will also be investigated. A simple Optimum Interpolation precipitation analysis will be
developed for this purpose. This will permit to estimate the uncertainties in the root zone soil moisture profile
as support to the validation SPs.
