MeteoInfo need to be pre-installed. The MeteoInfo and IMEP can be downloaded from http://www.meteothink.org/downloads/index.html. Unzip and copy "imep" folder into "MeteoInfo -> toolbox" folder.
IMEP is a model evaluation toolbox of MeteoInfo. The methods of continuous, dichotomous,
multicategory and score are supported.
IMEP jython script can be running in MeteoInfoLab environment.
Continuous and dichotomous verification:
import imep
datadir = 'D:/MyProgram/java/MeteoInfoDev/toolbox/IMEP/imep/sample'
fn = os.path.join(datadir, 'ex1.csv')
table = DataFrame.read_table(fn, delimiter=',', format='%3i%5f%i')
obs = table['Obs'].values
fcst = table['GFSMean'].values
print 'Continuous verification...'
cmethod = imep.verifymethod(method='continuous')
ctable = imep.verifytable(obs, fcst, cmethod)
print ctable
print 'Dichotomous verification...'
dr = imep.datarange(min=8) # >= 8
dmethod = imep.verifymethod(method='dichotomous', drange=dr)
dtable = imep.verifytable(obs, fcst, dmethod)
print dtableOutput from the script:
