Description

Prepares weather station data 2

Usage

read.WSdata2(WSdata, ..., height = 2.2, lat, long, elev, columns = c("date", "time", "radiation", "wind", NA, "RH", "temp", "pp"), date.format = "%d/%m/%Y", time.format = "%H:%M:%S", datetime.format = "%Y-%m-%d %H:%M:%S", tz = "", cf = c(1, 3.6, 1, 1), MTL)

Arguments

WSdata
csv file with weather station data
...
additional parameter to pass to read.csv()
height
weather station sensors height in meters
lat
latitude of weather station in decimal degrees. Negative values for south latitude
long
longitude of weather station in decimal degrees. Negative values for west longitude
elev
elevation of weather station in meters
columns
columns order of needed data. Vector containing "date", "time", "radiation", "wind", "RH" and "temp". Other values are ignored. If you have a column with date and time in the same column, you can include "datetime" and "date" and "time" are no longer needed.
date.format
date format. See strptime format argument.
time.format
time format. See strptime format argument.
datetime.format
datetime format. See strptime format argument.
tz
timezone of the weather station dates. If not present assumes the same timezone as the computer running the code. See strptime for details.
cf
conversion factor to convert radiation, wind, and temperature to W/m2; m/s and Celsius. See Details.
MTL
Metadata file. If not provided will look for one on working directory. If provided or present will calculate weather conditions on satellite flyby.

Details

For cf, if your data is in W/m2, km/h and Celsius (radiation, wind, temperature), cf should be: cf = c(1,0.2777778,1)
