Selected MODIS sinusoidal grid product subdataset name selector. Four presets are supported. custom_sel supersedes presets of product values.

Usage

process_modis_sds(
  product = c("MOD11A1", "MOD13A2", "MOD09GA", "MCD19A2"),
  custom_sel = NULL,
  ...
)

Arguments

product

character(1). Product code.

custom_sel

A character object that conforms to the regular expression. Details of regular expression in R can be found in regexp.

Note

Preset product codes and associated variables include

  • "MOD11A1" - Land surface temperature (LST)

  • "MOD13A2" - Normalized Difference Vegetation Index (NDVI)

  • "MOD09GA" - Surface reflectance, and

  • "MCD19A2" - Aerosol optical depth (AOD).

For a full list of available MODIS product codes, see the "Short Name" column at NASA LP DAAC Search Data Catalog. When utilizing a product code from this "Short Name" column, do not include the version number following the period. For example, if "Short Name" = MCD12C1.006, then product = "MCD12C1".
