calmet_upper_air: Create an upper air data file for CALMET

Description

This function retrieves upper air sounding data and processes it to generate an upper air input file for CALMET.

Usage

calmet_upper_air(location_name, year, lat_dec_deg = NULL,
  lon_dec_deg = NULL, lat_lon_grid_loc = 1, domain_width_m = NULL,
  domain_height_m = NULL, cell_resolution_m = 250, time_offset,
  READ62_exec_location)

Arguments

location_name

an assigned name for the CALMET domain.

year

the year for the UP.DAT file.

lat_dec_deg

the latitude of the CALMET domain in decimal degrees. The location of this point is defined in the lat_long_grid_loc argument.

lon_dec_deg

the longitude of the CALMET domain in decimal degrees. The location of this point is defined in the lat_long_grid_loc argument.

lat_lon_grid_loc

the location of the lat/long inputs in relation to the domain. Choices are: 1 (center), 2 (lower left), 3 (lower right), 4 (upper left), 5 (upper right).

domain_width_m

the width of the meteorological domain in meters.

domain_height_m

the height of the meteorological domain in meters.

cell_resolution_m

the grid cell resolution in meters.

time_offset

the offset from UTC-00:00 in hours.

READ62_exec

if the READ62 executable is in the system path, provide the name of the executable only; otherwise, provide the full path and name of the READ62 executable.
