pressure_conversion_station: Daily surface and mean sea level pressure conversion for CDT...

In rijaf-iri/CDT: Climate Data Tools

Daily surface and mean sea level pressure conversion for CDT station data format.

Description

Function to convert surface and mean sea level pressure in both way.

Usage

pressure_conversion_station(
  convert = "sfc2msl",
  pres.data = list(file = "", sep = ",", na.strings = "-99"),
  temp.from = "minmax",
  tmax.data = list(file = "", sep = ",", na.strings = "-99"),
  tmin.data = list(file = "", sep = ",", na.strings = "-99"),
  tmean.data = list(file = "", sep = ",", na.strings = "-99"),
  elev.from = "netcdfDEM",
  elev.data = list(file = "", varid = "z", ilon = 1, ilat = 2),
  output = list(file = "", sep = ",", na.strings = "-99")
)

Arguments

convert	character, the direction of conversion. Valid options: "sfc2msl" and "msl2sfc". "sfc2msl": conversion from surface to mean sea level pressure. "msl2sfc": conversion from mean sea level to surface pressure.
pres.data	named list, providing the pressure data in CDT station data format. Units: hPa. file: character, full path to the file containing the stations data sep: character, column separator of the data na.strings: character, missing values flag
temp.from	character, source of temperature data. Valid options: "minmax" and "mean". "minmax": the mean temperature is computed from the minimum and maximum temperature. "mean": the temperature data is from a mean temperature data.
tmax.data	named list, if temp.from is equal to "minmax", providing the maximum temperature data in CDT station data format. Units: degree Celsius. See pres.data for the elements of the list.
tmin.data	named list, if temp.from is equal to "minmax", providing the minimum temperature data in CDT station data format. Units: degree Celsius. See pres.data for the elements of the list.
tmean.data	named list, if temp.from is equal to "mean", providing the mean temperature data in CDT station data format. Units: degree Celsius. See pres.data for the elements of the list.
elev.from	character, source of the elevation data. Valid options: "inputPresData", "cdtCrdFile" and "netcdfDEM". "inputPresData": the elevation data is from the pressure data. "cdtCrdFile": the elevation data is from a CDT coordinates file. The ID must be the same as the pressure data. "netcdfDEM": the elevation data is from the pressure data. Default is "netcdfDEM".
elev.data	named list, if elev.from is equal to "cdtCrdFile", providing the CDT coordinate file containing the elevation data. Units: meters. file: character, full path to the CDT coordinate file sep: character, column separator of the data na.strings: character, missing values flag If elev.from is equal to "netcdfDEM" set the elements of the list providing the Digital Elevation Model in netCDF format. Units: meters. file: character, full path to the netCDF file containing the elevation data. varid: character, name of the variable to read from the netCDF data. ilon: integer, order for the longitude dimension of the variable. ilat: integer, order for the latitude dimension of the variable.
output	named list, the elements of the list are file: character, full path to the file to save the converted pressure sep: character, column separator of the data na.strings: character, missing values flag
