# Soil Water Content 1000 m

Planet — version 5.0

## Description

This dataset quantifies soil water content (m³/m³) at 1000 m spatial resolution. Data has global coverage and sub-weekly resolution, available from 2002 onwards. Data includes includes pixel-level quality flags to indicate whether an observation has been critically flagged or not.

## Summary

- **ID:** 667729d4-8a68-490f-905e-3f8190fe36c7
- **Type:** Raster
- **CRS:** EPSG:4326
- **Spatial coverage:** Global
- **Spatial resolution:** 1 km
- **Temporal coverage:** 2002+
- **Temporal resolution:** Sub-weekly

## Usage notes

New time points are delivered near real-time. Soil water content is delivered in three variables, one for each radar frequency band used to measure it (L-band, C-band, X-band). Actual temporal coverage differs among variables due to differences in satellite data coverage. Actual temporal resolution varies depending on satellite pass rate. Unreliable values are critically flagged but may still be inaccurate in urban areas, near dynamic water bodies, and on slopes > 20°.

## Variables

### c_critically_flagged
- **Type:** uint16
- **NoData:** 65535
Indicates whether C value has been critically flagged.

### c_value
- **Type:** uint16
- **Units:** m³/m³
- **NoData:** 65535
Total amount of water in the soil, as measured using the C-band (6.9 GHz) of the AMSR-E and AMSR-2 satellite instruments. The C-band has a sensing depth of ~2 cm and is sensitive to vegetation density, so is suited to use cases in short vegetation.

### l_critically_flagged
- **Type:** float32
- **NoData:** 65535
Indicates whether L value has been critically flagged.

### l_value
- **Type:** float32
- **Units:** m³/m³
- **NoData:** 65535
Total amount of water in the soil, as measured using the L-band (1.4 GHz) of the SMAP satellite. The L-band has a sensing depth of ~5 cm, is sensitive to change, and is insensitive to vegetation density.

### x_critically_flagged
- **Type:** uint16
- **NoData:** 65535
Indicates whether X value has been critically flagged.

### x_value
- **Type:** uint16
- **Units:** m³/m³
- **NoData:** 65535
Total amount of water in the soil, as measured using the X-band (10.7 GHz) of the AMSR-E and AMSR-2 satellite instruments. The X-band has a sensing depth of ~1 cm and is sensitive to vegetation density, so is suited to use cases in short vegetation.

## Pricing

This dataset adds a new time point every sub-weekly. A new subscription 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:
