sef2climatol: Convert SEF data files to 'climatol' input files.

In climatol: Climate Tools (Series Homogenization and Derived Products)

Convert SEF data files to climatol input files.

Description

This function reads all SEF files contained in a directory and writes their data in *.dat and *.est climatol input files.

Usage

  sef2climatol(dr,Vbl,varcli=Vbl,ndec=1,na.strings="NA",mindat=NA)

Arguments

dr	directory containing the SEF files
Vbl	name of the variable in the SEF files
varcli	name of the variable in the climatol destination files
ndec	number of decimals to save
na.strings	missing data codes (specified as quoted strings)
mindat	minimum required number of data per station

Details

SEF (Station Exchange Format) is the Copernicus Climate Change Service format for Data Rescue projects. Visit https://datarescue.climate.copernicus.eu/node/80

Missing elevations will be assigned the value 99

Some files may contain a single quotation mark in the metadata field, causing not reading the end of line until a pairing quoting is found in the following line, hence skipping half of the data. Parameter quote='\' has been set in the reading command as a workaround.

All data are dumped into a temporary file named SEFdata.csv, which is used by the function csv2climatol to write the input files for climatol.

Examples

## Set a temporal working directory and write input files:
wd <- tempdir()
wd0 <- setwd(wd)

## Create a directory and copy all SEF files to be processed:
dir.create('dir1')
file.copy(exampleFiles('GHCN_v4_Bhamo.tsv'),'dir1')
file.copy(exampleFiles('GHCN_v4_Diamond_Island.tsv'),'dir1')

## Now run the function:
sef2climatol('dir1','ta')

## Return to user's working directory:
setwd(wd0)

## Input and output files can be found in directory:
print(wd)
