Usage

1

Format

An object of data.frame class with 122 records with the following variables:

YearMonth

year and month during which the method was applied, with a required date format of YYYYMM.

ETMethod

Identifier that indicates the method used to estimate ET values. Identifiers include either “Allen-Robison”, the Allen and Robison method (Allen and Robison, 2007); “METRIC”, the Mapping Evapotranspiration at high Resolution and with Internalized Calibration (METRIC) model (Allen and others, 2010a); “NDVI”, the Normalized Difference Vegetation Index (NDVI) method (Allen and others, 2010b); “Interpolation”, interpolation from known ET data; or “METRIC-NDVI”, a combination of METRIC and NDVI methods.
