Extract climate data of TerraClimate

Description

A function that extract a time series of climate variables (1958-01-01T00:00:00Z - 2021-12-01T00:00:00).

Usage

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

Arguments

to, from	it's a string object,starting and final date.
by	two types of increment of the sequence by month and year.
band	name of band.
region	is a feature or feature collection.
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.

• aet (mm): Actual evapotranspiration, derived using a one-dimensional soil water balance model.

• def (mm): Climate water deficit, derived using a one-dimensional soil water balance model.

• pdsi : Palmer Drought Severity Index.

• pet(mm): Reference evapotranspiration (ASCE Penman-Montieth).

• pr (mm): Precipitation accumulation.

• ro (mm): Runoff, derived using a one-dimensional soil water balance model.

• soil (mm): Soil moisture, derived using a one-dimensional soil water balance model.

• srad (W/m²): Downward surface shortwave radiation.

• swe (mm): Snow water equivalent, derived using a one-dimensional soil water balance model.

• tmmn (°C): Minimum temperature.

• tmmx (°C): Maximum temperature.

• vap (kPa): Vapor pressure

• vpd (kPa): Vapor pressure deficit.

• vs (m/s): Wind-speed at 10m.

Value

a tibble object with the new variables.
