sat: Functions to model evaluation using satellite

Description

functions to evaluate the spatial performance using satellite

Usage

sat(
  mo,
  ob,
  rname,
  table = NULL,
  n = 6,
  min = NA,
  max = NA,
  method = "bilinear",
  eval_function = stat,
  mask,
  verbose = TRUE,
  ...
)

Value

a data.frame

Arguments

mo

SpatRaster or raster with model

ob

SpatRaster or raster with observations

rname

passed to stat

table

data.frame to append the results

n

number of points from the boundary removed, default is 5

min

minimum value cutoff

max

maximum value cutoff

method

passed to terra::resample

eval_function

evaluation function (default is stat)

mask

optional SpatVector to mask the results

verbose

set TRUE to display additional information

...

other arguments passed to stat

Examples

model_o3 <- terra::rast(paste0(system.file("extdata",package="eva3dm"),
                              "/camx_no2.Rds"))
omi_o3   <- terra::rast(paste0(system.file("extdata",package="eva3dm"),
                              "/omi_no2.Rds"))

# generate the statistical indexes
sat(mo = model_o3,ob = omi_o3,rname = 'NO2_statistical')

# generate categorical evaluation using 3.0 as threshold
sat(mo = model_o3,ob = omi_o3,rname = 'NO2_categorical',
    eval_function = cate, threshold = 3.0)
