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
