NOAA NCDC global summary of the day GSOD for rainfall in iotools

[mikofski]

NOAA NCDC database of GSOD data has daily rainfall that is useful for determining soling rates based on Addie Kimber's dynamic soiling model. There used to be an ftp site, but I didn't look too hard for it.

Is there a chance that some one from SunPower, like @cedricleroy or @anomam , could dig through the pvlife github repo and extract the gsod code and add it to iotools - or post it to a gist so that someone else can work it into shape for pvlib.iotools?

thanks!

Nit - that's NOAA database, not NREL. The link is correct.

If it's already useful for PV modelers that's fine with me. I am not picky about what goes into iotools but I don't want it to be a dumping ground for random weather data. Unless I missed something GSOD does not have irradiance or aerosol data, so it might be better placed in a package like Unidata's Siphon

I only used it for daily rainfall in the soiling model. If there's a better source of rainfall data, then this probably isn't needed. If it's not useful for pvlib, I can open an issue for it at Siphon, if it's not already there.

I think the noaa ncdc isd also has global rainfall

@kandersolar With the addition of #1767, is the GSOD dataset mentioned here still desirable? I'm unsure if they retrieve data from the same source.

I browsed through the list of available stations for Denmark as an example and saw only partial overlap with what ACIS makes available, so I think #1767 does not make this issue redundant.
