read.WSdata2: Prepares weather station data 2

In midraed/water: Actual Evapotranspiration with Energy Balance Models

Description

Prepares weather station data 2

Usage

read.WSdata2(
  WSdata,
  ...,
  height = 2.2,
  lat,
  long,
  elev,
  columns = c(date = 1, time = 2, radiation = 3, wind = 4, RH = 6, temp = 7, rain = 8),
  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", "temp" and "rain". 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)
