Soil moisture data covering the whole area of Luxembourg for the first 1-2 cm, as well as 5-10 cm soil depth:

• C and X band for the first 1-2 cm soil depth.
• L-band for the first 5-10 cm of soil depth.

with a resolution of 100 x 100 m per pixel and with a temporal resolution of "once per day" and an average number of 280 images per year images per year (as a combination of C, X and L-band sources)

Details

* pixel size is given as a number in meters. This is an approximate size as the data itself is stored in decimal degrees (WGS84). The actual size in decimal degrees is given in the description of each data product.

Description of the files

Every file name encodes the characteristics of the file:

• SM-SMAP-LN-DESC: Volumetric Soil Moisture L-band (SM) / Satellite observed volumetric soil moisture derived from L-band microwave data in combination with other bands. It is based on VanderSat's patented high-resolution technology and provides soil moisture of the top 5 cm of the soil depending on moisture conditions. VanderSat’s L-band data is retrieved from the SMAP satellite.
• SM-AMSR2-C1N-DESC: Volumetric Soil Moisture C-band (SM) / Satellite observed volumetric soil moisture derived from C-band microwave data in combination with other bands. It is based on VanderSat's patented high-resolution technology and provides top soil soil moisture of the top 2 cm of the soil depending on moisture conditions. VanderSat's C-band soil moisture is derived from the Advanced Microwave Scanning Radiometer 2 (AMSR2) on board the GCOM-W1 satellite as well the Advanced Microwave Scanning Radiometer - EOS (AMSRE) on board the AQUA satellite.
• SM-AMSRE-C1N-DESC: Volumetric Soil Moisture C-band (SM) / Satellite observed volumetric soil moisture derived from C-band microwave data in combination with other bands. It is based on VanderSat's patented high-resolution technology and provides top soil soil moisture of the top 2 cm of the soil depending on moisture conditions. VanderSat's C-band soil moisture is derived from the Advanced Microwave Scanning Radiometer 2 (AMSR2) on board the GCOM-W1 satellite as well the Advanced Microwave Scanning Radiometer - EOS (AMSRE) on board the AQUA satellite.
• SM-AMSR2-XN-DESC: Volumetric Soil Moisture X-band (SM) / Satellite observed volumetric soil moisture derived from X-band microwave data in combination with other bands. It is based on VanderSat's patented high-resolution technology and provides top soil soil moisture of the top 1 cm of the soil depending on moisture conditions. VanderSat's X-band soil moisture is derived from the Advanced Microwave Scanning Radiometer 2 (AMSR2) on board the GCOM-W1 satellite, the Advanced Microwave Scanning Radiometer - EOS (AMSRE) on board the AQUA satellite and the GMI sensor on board the Global Precipitation Measurement (GPM) satellite.
