If it wasn't for DST I would be home before 7:00. :mad:

I should have batched it. Dammit.

What are you supposed to be doing with this stuff? I mean, what's the purpose? What is it being ingested for?

Analysis, man, analysis!

Specifically, validation of the GPCP product over mountainous terrain for rain and snow. The rain vs. snow thing is the tricky part, because most SNOTEL sites just give you daily gauge and snow pillow totals. The snow pillow measures snowmass, but rain or snow can cause an increase in snowmass (or not, depending on melting). As a quick and dirty way of determining if precip was rain or snow I used the min/max temp data. If the daily max is less than -2 C I call that a snow day, and if the daily min is greater than 2 C I call that a rain day. Days in the middle are indeterminate. The biggest fly in the ointment for this technique is freezing rain, so I've been looking at freezing rain climatology for the area of interest to determine how much of a factor it is. Hopefully I'll get a journal article out of this stuff.
