Dear Users,

the H SAF Team is pleased to announce that the new H SAF ESCAT-ASCAT Root-zone Soil Moisture Climate Data Record 0.1 deg sampling product (ID: H145) is now available on EUMETCast, covering the period 1991-2024. The data record extension (ID: H146) is available from 2025 and is updated daily with a 5-day latency.

The products are based on level 2 ESCAT-ASCAT SM assimilation from the ERS/Metop satellites. Expressed as a liquid soil wetness index over 4 layers from the surface down to 2.89 m.

The H145 and H146 products succeed the H141 (RZSM-DR2019-10km) and H142 (RZSM-DR-EXT-10km) products

Main characteristics of ESCAT-ASCAT RZSM DR v3 0.1 deg (H145) and ESCAT-ASCAT RZSM DR v3 EXT 0.1 deg (H146):

Variable: Soil moisture content in the root-zone (0-289 cm depth)

Unit: Liquid soil wetness index(0–1)

Spatial sampling/resolution: 0.1 degrees

Vertical sampling: 4 layers with depths of 0-7 cm, 7-28 cm, 28-100 cm, and 100-289 cm

Spatial coverage: Global (65°S, 180°W, 80°N, 180°E)

Timeliness: 5 days (for the H146 ICDR)

Format: netCDF4
