DAILY CLIMATE REPORT - issued daily:
Detailed daily weather statistics (usually for yesterday), including temperature, precipitation, degree days, wind, humidity, sunrise/sunset, and record temperature data for the following day. Precipitation data includes both calendar year and water year totals, percent of normal values, and comparisons to normal. This product is available for up to 2 months.
The material on this site is an outgrowth of several previous manuals prepared by Division of Water staff. It includes information on precipitation amounts, adjustment, and distribution for heavy storms. The expanded isohyets are the result of linear interpolation and do not indicate increased accuracy from the source documents.
NCDC (National Climatic Data Center) - the world's largest active archive of weather data. NCDC produces numerous climate publications. Mostly open access, but some data sets come with a fee.
