Metop-C ASCAT NRT SSM 25 km sampling

Soil moisture content in the surface layer (0.5-2 cm) express in degree of saturation (0 – 100 %) generated from ASCAT Metop-C at 25 Km sampling, processed shortly after each satellite orbit completion. Commitment and validation restricted to following conditions: low to moderate vegetation regimes, unfrozen and no snow, low to moderate topographic variations and no wetlands and coastal areas.

• Coverage: global
• Cycle: ≈3 minutes
• Resolution: 50 km x 50 km
• Accuracy: threshold S/N 3 dB, target S/N 3 dB, optimal S/N 6 dB
• Timeliness: 2 hours
• Dissemination: FTP, EUMETCast (type NRT)
• Formats: Values in grid points of specified coordinates in the orbital projection (BUFR, EPS Native, NetCDF)
