About the Data
Precipitation Network data are daily precipitation data, collected for the 24-hour period midnight to midnight on the given day. For example, the reading on 1/1/2005 is valid at 11:59 p.m. of that day.

How to Search for Data
The Precipitation Network Data web site was designed to provide precipitation data in a usable format that is easy to view or download. Begin by selecting up to five stations in the "Choose up to five stations" area. Next, specify the range of years under "Choose a range of years". Lastly, click the "Get Data" button. Your data will be displayed on the "Data Results" page.

Data Search Tips
Retrieving data over a span of the entire database, or a very large part of it, may require a fast Internet connection. If you access the Internet via modem and are having trouble viewing or downloading data, try limiting your search to only a few years at a time. Using this technique, you will be able to download "chunks" of the data to your computer. After you retrieve all of your desired data, you can then "assemble" it into a single text file on your own computer.

Making & Downloading a Data Text File
After you perform a data search, you can create a text file and download it to your computer. This text file may be imported into any spreadsheet program accepting a comma-delimited format. Once you are viewing data on the "Data Results" page, locate and click the button at the bottom of the page titled "Make this a Text File". The resultant page will display the message "CREATING FILE". Once the "FILE CREATED" message has been displayed, your text file has been created. Your file will be named using a string of numbers, followed by ".txt". You may download the text file by right-clicking on it and choosing "Save Link As..." (Firefox/Mozilla/Netscape) or "Save Target As..." (Internet Explorer/Opera).

How to Download Data
Please see "Making & Downloading a Data Text File" above.
