Climate Inventory Map Information and Instructions

The purpose of the Climate Inventory Map is to assist users in finding climate data and past weather information by allowing users to create maps for various climate variables (temperature, precipitation, etc.) for Washington and its 50 mile surroundings. Users select the map of interest (example: daily temperature data) then select a station, at which point information on the station as well as instructions on obtaining data from that station are available. Only active stations are plotted and no data can be directly downloaded from these maps. You must use the instructions corresponding to the station to access the data.

Currently, the climate variables that are available include temperature, precipitation, wind, snow, solar radiation, dewpoint/humidity, cloud cover, and other (may include soil moisture, pressure, and/or evaporation data).

The climate inventory map is produced using the Google Maps API with a combination of PHP and MySQL to plot the stations.

Station Information & Data Access Instructions

When a marker or point corresponding to a station is clicked on, a 'balloon window' appears with information about the station. To close the balloon window, click the 'X' icon in the upper right corner of the balloon window or simply click on another station.

To view the instructions on how to get data from the station, click on the 'Access Data' tab at the top of the balloon window. You will now see a 'Primary Source' and a 'Secondary Source' with the month (not in all cases) and the year in which data began being archived. To access the data, click where it says 'Click Here' under the 'Data Access Instructions'.

Once the instruction link is clicked, a window with instructions on how to access the data for that station will pop-up. Note users that have pop-up blockers enabled, may not see the pop-up window with the instructions displayed and will have to consult the documentation for their web browser or popup blocker to view the instructions. Users of Firefox 1.0 will have to turn off their pop-up blocker or enter an exception for the site (refer to the Firefox documentation for assistance). Firefox 1.5 users will likely not encounter this problem.

The instructions are displayed at the top of the window (top frame). Follow the instructions exactly as they are listed in order to access the data. In some cases there will be multiple methods to obtain data for a particular station. Use the scroll bars to the right of the instructions to view the additional methods. You may have to refer back to the map page where the balloon window is located for that station and click the 'Station Link' to obtain the data. When the station link is clicked, the website will appear in the same pop-up window just below the instructions. The top frame where the instructions resides, can be resized if necessary.
