Reference and Potential Evapotranspiration

Evapotranspiration can be computed as reference, potential, or actual evapotranspiration.   Reference evapotranspiration is that from a grass surface that is well-watered.  Potential evapotranspiration is that from a surface that has unlimited water (such as a lake). 

Reference and potential evapotranspiration are computed at a 2-kilometer spatial resolution and daily timestep for the...

Hurricanes

Preventing flood hazards, such as hurricane-induced tidal surge, from becoming human disasters requires an understanding of the relative risks floods pose to specific communities and knowledge of the processes by which flood waters rise, converge, and abate. Historically, hurricane-induced tidal surge has been documented through measurement of high-water marks left on structures or vegetation...

The degradation of coastal habitats, particularly coral reefs, raises risks by increasing the exposure of coastal communities to flooding hazards during storms.
