Arcola Data

About


The Arcola data site was initiated in the summer of 2002 to collect weather and climate data. The site is funded by the C-FAR Water Quality Strategic Research Initiative (WQSRI). The goal of the site is to measure and archive water and nitrogen balances.

Data collection ceased in August 2006 for this station, and are provided on this site as an archive.

Archived data from the site are structured into a comma-delimited format for ease of importation into most spreadsheet applications. Beginning dates vary. Data column headers are defined below.

Average data are calculated from the polling of instrumentation every 10 seconds and averaging over each hour and day. Maximum and minimum data are the single highest and lowest values recorded for the day within each variable. Solar radiation, precipitation, and evaporation represent a daily total of these parameters.

Headers ending with "er" are error flags with the options of "M" for missing data and "E" for estimated data. Where appropriate, missing data were estimated from adjacent station data or interpolated from adjacent times at the same site.

Arcola Site data are currently available on the web in two formats. Monthly data for the current year in space-delimited or column-delimited text files are formatted just as a paper copy would appear.

Yearly data, the second format, list daily data two different ways. The "archived" format lists daily data from the time the station began recording until the last complete year of collection. The current year's daily data also are presented in the same format. Both types of text files are in comma-delimited format.

To Print the Data:

First, Save the data file (or text file) to your hard drive. Use your Web browser to navigate to the page displaying the data you wish to print. Choose File --> Save As, and then in the resulting "Save As" box, choose a location on your hard drive to Save the file. Click Save, which will put the text file on your computer's hard drive.

Once you have saved the text file on your hard drive, open the file in WordPad. To start WordPad go to Start --> Programs --> Accessories --> WordPad. To open the file, use File --> Open, and then in the "Open" box, navigate to the location where you saved the file during the last step. Select the file, and click Open. Select, or highlight, the entire page using Edit --> Select All. When selected, the text area will change to a black background with white lettering.

Change the font size by typing 7.4 into the font size box and press Enter. The font size box is directly to the right of the font bar (which probably displays 10-point "Courier New" or "Courier"). If these bars are not available, click View --> Format Bar. If the text will not fit on the printed page, then try reducing the point size to 7.3. Keep reducing the size of the font by 0.1 until the page prints correctly. If the data are still selected (black) in the document body, click anywhere in the document text area to deselect it.

The page is now ready to print by using File --> Print. If the data are monthly and will not fit on a single 8½ X 11 page, reduce the margin width. This may be changed in the "Page Setup" area (File --> Page Setup) by entering values of 0.25 inches for the left and right margin widths.
