IMD heat exposure indicators for a bounding box

Description

Downloads IMD gridded daily maximum and minimum temperature (1 degree) for the requested years and the baseline, then computes exposure_indicators() for each grid cell.

Usage

IMDExposureBbox(...)

imd_exposure_bbox(
  start_year,
  end_year,
  north,
  south,
  east,
  west,
  baseline = c(1991, 2020),
  ...,
  output_dir = tempdir(),
  use_cache = TRUE
)

Arguments

...	Further arguments to exposure_indicators(), such as months, period, heatwave_method, terrain or hill_elevation; terrain is classified per 1 degree cell.
start_year, end_year	Years to report (1951-2025).
north	Latitude of the north boundary.
south	Latitude of the south boundary.
east	Longitude of the east boundary.
west	Longitude of the west boundary.
baseline	Climatology years, c(first, last), for normals and percentiles.
output_dir	Directory for the output files (default: tempdir()).
use_cache	If TRUE, use the cached data when it is available (default: TRUE).

Value

The data.frame of exposure_indicators() for start_year to end_year, one row per grid cell (latitude, longitude) and period.

Examples

jaipur <- imd_exposure_bbox(2022, 2024,
  north = 28, south = 26,
  east = 77, west = 75, months = 3:6
)
