Soil Water Content 20 m
Description
This dataset quantifies soil water content (m³/m³) at 20 m spatial resolution. Data has global coverage and sub-weekly resolution, available from 2018 onwards.
0dfb63a2…Usage notes
New time points are delivered near real-time. This dataset is intended for agricultural use cases. Actual temporal resolution varies depending on satellite pass rate. Data is downscaled to 20 m spatial resolution to reduce signal mixing between fields. For best results, an area of interest (AOI) should be a single field of interest. Values may be unreliable in urban areas, near dynamic water bodies, and on slopes > 20º. AOIs must be < 3000 ha.
Variables
value
Description
The total amount of water in the soil, as measured using the L-band (1.4 GHz) of the SMAP satellite combined with the C-band (6.9 GHz) and X-band (10.7 GHz) of the AMSR-2 satellite instrument. The combination of these bands is intended for agricultural use cases with an overall sensing depth of ~5 cm.
Usage notes
Overall reported accuracy is ± 0.04 m³/m³. Data is downscaled to 20 m spatial resolution at the field level to reduce signal mixing between fields. For best results, an AOI should be a single field of interest. Temporal resolution varies between 137 and 228 observations per year depending on AOI latitude. On each date, observations are at 6:00 am local solar time.
Pricing
This dataset adds a new time point every sub-weekly. A data request returns the full archive up to the most recent time point and creates a one-year subscription to future time points. Data acquisition costs are per hectare:
