FM.readPrecip: Load Precipitation Data

Description

After all rasters (DEM, land cover, and soil) are loaded, users may use this function to load precipitation data. Precipitation data can come from multiple weather stations or gridded remote sensing data.

Usage

FM.readPrecip(datatype = 0, txtfile, startdatetime, enddatetime, 
    interval, idwpower = 2)

Arguments

datatype

0 = weather stations, 1 = raster data from NWP models, reanalysis datasets, or other remote sensing datasets.

txtfile

full file path of the text file required for precipitation data. If the data comes from multiple weather stations, the format of this text file should be given as follows: #: ------------------------------------------ #: ID Lon Lat Datafile #: 1 -92.0296 30.1800 p1.txt #: 2 -92.0260 30.1779 p2.txt #: 3 ... ... ... #: ------------------------------------------ If the precipitation data comes from rasters, the format of this text file should be given as follows: #: ------------------------------------------ #: ID Rasterfile #: 1 p_2016-06-09_12-00-00.tif #: 2 p_2016-06-09_13-00-00.tif #: 3 ... #: ------------------------------------------

startdatetime

start datetime of precipitation records, should be formated as "YYYY-MM-DD hh:mm:ss". E.g., "2016-06-09 12:00:00".

enddatetime

end datetime of precipitation records, should be formated as "YYYY-MM-DD hh:mm:ss". E.g., "2016-06-09 13:00:00".

interval

interval of precipitation records, unit: seconds. For example, 1 hr = 60 min * 60 sec = 3600 sec.

idwpower

(OPTIONAL) the power of IDW method, default: 2, suggested options: 1, 2, or 3.
