Colorado daily precipitation accumulations
Description
Three objects: 1) COprcp, a 404,326-row
data frame with columns date, prcp and meta_row;
2) COprcp_meta, a 64-row data frame, with meta data for 64 stations.
3) COelev, a list of elevation for the domain at 0.02 x 0.02
degree resolution. Precipitation amounts are only given for April
to October in the years 1990 - 2019. The domain has a longitude range
of [-106, -104] and a latitude range [37, 41]. These choices reflect
the analysis of Cooley et al. (2007).
Usage
data(COprcp) # loads all three objects
Format
A data frame with 2383452 rows and 8 variables
The variables are as follows:
- date
date of observation
- prcp
daily rainfall accumulation in mm
- meta_row
an identifier for the row in COprcp_meta; see ‘Examples’
- lon
longitude of station
- lat
latitude of station
- elev
elevation of station in metres
- id
GHCDN identifier

brks <- pretty(COelev$z, 50)
image(COelev, breaks=brks, col=rev(heat.colors(length(brks[-1]))))
colplot(COprcp_meta$lon, COprcp_meta$lat, COprcp_meta$elev, breaks=brks, add=TRUE)
