Description
The Short Term Current Drought Risk product captures the current risk of drought across the globe using a well-established drought monitoring metric, the Standardized Precipitation Index (SPI). Current Drought Risk products seek to identify global areas where current drought conditions may cause losses to agriculture; affect the supply of water, energy production, public health and wildlife; or contribute to wildfire conditions.
Technical Description
The Short Term Current Drought Risk product captures the current risk of drought across the globe using the Standard Precipitation Index (SPI), a well-established drought monitoring metric, across a combination of 3-, 6-, 9-, and 12-month accumulation periods. By using shorter accumulation periods of the SPI, the product is built to capture drought that is likely to affect vegetation or agricultural systems. The v2.0 product improves the resolution of the v1.0 product from 110 km to 11 km and provides enhanced global coverage.
This dataset contains the following fields:
- drought_class: The drought classification for each pixel location. The values are integers from 0-4 representing the drought classes of no drought (0), mild drought (1), moderate drought (2), severe drought (3), and extreme drought (4). The Short Term Current Drought layer uses shorter aggregation periods of drought indices to capture drought that is likely to affect vegetation or agricultural systems.
