Caribbean Evaporative Demand Drought Index

<p>ERA5-Land derived pentad evaporative demand drought index (EDDI) for the Caribbean from 1981-2021. EDDI is calculated following Hobbins et al. 2016 and the underlying input data are acquired from ERA5-Land (Muñoz-Sabater 2021). This version of EDDI calculates hourly ASCE reference evapotranspiration for a short reference surface following Allen et al. 2005. Leap days have been removed.</p> <p><br></p> <p>This dataset was produced by first creating hourly reference evapotranspiration for a short reference crop for every grid point in the study domain following the equations laid out in Allen et al. 2005.</p> <p><br></p> <p>Allen, R.
