[ncl-talk] Error reading grib file

[Kacie Shourd]

My apologies, I just read some of the examples and print(f) should work. Perhaps there is an error in your data?

Is the only thing you are trying in your code "print(f)"??
I'm not sure that will work. Try adding something like this:

getfilevarnames(f)

or something else from the listed functions at https://www.ncl.ucar.edu/Document/Functions/Built-in/addfile.shtml

It may be reading your file after all, but the print statement isn't the way to access information in the file.

Hi Kacie,

Thank you! I tried adding adding different file extensions (.grib, .grib1 etc.), but none of them worked. For some unknown reason, the file still cannot be opened by addfile.

Best,
Xin

Hi, Xin!

Try adding the file extension, like this:

f = addfile("./gage.hrly.prcp.20020101.grib1","r")

Best,
Kacie

Dear All,

I'm looking at the 4km resolution hourly precipitation from NCEP/CPC (http://rda.ucar.edu/datasets/ds507.5/). The documented data format is GRIB1, but when using "addfile" no variables were printed.

ncl 0> f = addfile("./gage.hrly.prcp.20020101","r")
ncl 1> print(f)

Variable: f
Type: file
(0) File Missing Value : -1


Does anyone have a clue how to access the data?
Thank you all!

Best,
Xin
