Title
Ethiopia - Palmer Drought Severity Index (PDSI)
Description
This dataset provides Palmer Drought Severity Index (PDSI) values for Ethiopia from 2020 to 2024, offering insights into drought conditions across the country. The PDSI is a widely used drought index that measures deviations in soil moisture conditions from the long-term average, helping to identify both drought and wet conditions. Unlike traditional PDSI calculations that rely on the Thornthwaite method for estimating potential evapotranspiration (ET), this dataset utilizes a more physically based Penman-Monteith reference ET, which accounts for: * Solar radiation * Temperature * Humidity * Windspeed ## Interpretation of PDSI Values: * PDSI between -0.5 and 0.5 → Near-normal soil moisture conditions * PDSI < -4 → Extreme drought * PDSI > 4 → Very wet conditions
