In healthinnovation/lis: InnovaLab Toolkit

Extract evapotranspiration data of Modis

Description

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.

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

Value

a tibble object with the new variables.
