make_california_UCIPM_station_list: Makes a list of the UC IPM weather stations

Description Usage Value Author(s) References Examples

Description

Makes a list of the weather stations contained in the UC IPM database, with geographic coordinates. This requires parsing through quite a few websites, because the coordinates don't seem to be stored in one central (and easily accessible) place. Hence this is much slower than one might expect. A shortcut is the california_stations dataset supplied with chillR, which contains the result of running this function in February 2016. The default in the other relevant functions will be the use of this pre-stored list, but if the current station coverage is needed, this function can help. Having said this, station coverage probably won't change very rapidly, so in most cases, the california_stations dataset should be enough.
