Extract evapotranspiration data of Modis — get_etp • innovar

A function that extract a ETP time series of MODIS by month (2001-01-01T00:00:00Z - 2022-04-23T00:00:00).

Usage

get_etp(from, to, band, region, fun = "count", scale = 1000)

Arguments

to, from: it's a string object,starting and final date.
band: name of band.
region: region and object sf.
fun: function for extract statistic zonal (count, kurtosis, max,mean, median , min , mode , percentile, std, sum , variance, first).
scale: A nominal scale in meters of the projection to work in.

Value

a tibble object with the new variables.

Details

Name of some bands.

ET (kg/m²): Total evapotranspiration.
LE (J/m²): Average latent heat flux.
PET (kg/m²): Total potential evapotranspiration.
PLE (j/m²): Average potential latent heat flux.
ET_QC: Evapotranspiration quality control flags
