Medspiration MED-SOC-RS-001_1 System Requirements Document Issue F SR.CFD.0100/I Data in close proximity to rain, land, sea ice and at high wind speeds are flagged as suspect. SR.CFD.0110/I If a pixel is located within an area of known side lobe contamination as defined by sensor specific side lobe contamination maps, bit 0 of the L2P confidence data variable MW_SST_flags should be set. SR.CFD.0120/I If a side lobe contamination map is not available, any pixel within sidelobe_distance_threshold (specified in the L2P configuration file in km) from land should flagged as contaminated. Comment: A contamination map will be derived from the LPDAAC/LANDMASK at the mw SST field resolution till the appropriate map is made available by GHRSST. SR.CFD.0140/I If a pixel lies within a radius of relaxed_MW_rain_distance specified in km of a clearly flagged rain contaminated pixel, bit 1 of the L2P confidence data variable MW_SST_flags should be set. SR.CFD.0150/I If the difference between the most recent GHRSST-PP analysis SST and the potentially contaminated pixel is greater than relaxed_rain_threshold (K), the pixel should not be included in a L2P data file. Comment 1: A most recent analysis map will be derived from the CMS (Faugère eet al.) climatology until available from GHRSST. Comment 2: sidelobe_distance_threshold, relaxed_MW_rain_distance and relaxed_rain_threshold should be included in the configuration file. SR.CFD.0160/I If a TRMM TMI SST measurement value is less than 285K, bit 2 of the L2P confidence data variable MW_SST_flags should be set SR.CFD.0170/I If a microwave wind speed measurement contemporaneous with a microwave SST measurement is greater than 12 ms -1 , the wind flag which is the bit 3 of the L2P confidence data variable MW_SST_flags should be set. SR.CFD.0180/I If a contemporaneous microwave wind speed measurement is unavailable, the nearest NWP analysis in space and time to the SST measurement should be used to evaluate the wind flag defined above. SR.CFD.0190/I The distance (Dice) to the nearest Sea ice shall be computed. © 2004 SOC Page 38 of 193
Medspiration MED-SOC-RS-001_1 System Requirements Document Issue F SR.CFD.0200/I The distance to the nearest problem (Dpb=min(Dcont, Dice, Drain)) shall be computed SR.CFD.0210/I Derive MPCV value from Dpb and wspd on the scale shown in Table 3-1, using thresholds MPCV_wind1, MPCV_wind2 and MPCV_proximity. Table 3-1 Microwave proximity confidence value (MPCV) scale definitions. MPCV Value Description 10 Unprocessed: Data that have not been classified (measurement indicates sea ice) 11 Questionable: Data that are may be contaminated by land, rain, sea ice, RF interference, degraded due to uncertainty in seawater emissivity at higher wind speeds, and/or are below a low SST threshold. 12 Acceptable: Data that are far from land, rain, sea ice, RF interference and are within a favourable wind speed regime. 13 Diurnal: Data are far from any rain or land flags but are within a low wind speed regime where a cool skin or warm layer may influence the observed SST. SR.CFD.0220/I The threshold values MPVC_wind1, MPVC_wind2 and MPVC_proximity are in a configuration file. 3.2.5.2 Infrared case SR.CFD.0300/I If an indication of sun-glint is provided with an input SST pixel value, this should be used to set the SunGlint flag of the corresponding L2P confidence data record. SR.CFD.0310/I If an indication of sun-glint is not provided with an input pixel value, an appropriate method should be used to set the SunGlint flag of the L2P confidence data record that is based on the geometry of sun and satellite position and surface roughness (e.g., Gardashov and Barla, 2001) © 2004 SOC Page 39 of 193
