  8. Downloading from a NADP Raingage • Wait for the download: After the download completes, a message box will appear that displays the number of records downloaded. Click on the message box to clear it. • Change to the data page: Click on the data tab to view daily amounts • Select sample start/end times: The data tab will allow you to select the sample start and end dates and times. These are initialized to the first and last records that were just downloaded from the raingage. Adjust these to the correct values, select the appropriate network, and click the “Compute Daily Precipitation” button Click here to clear the message box (15) NADP Raingage Download Procedure

  9. Downloading from a NADP Raingage • View daily amounts: The daily precipitation amounts in inches will be displayed in a new window. If you selected AIRMoN as the network, hourly, rather than daily values will be displayed. • Scroll if needed: Not all of the data can be displayed in the window, so scroll bars are provided at the bottom and possibly the right side of the window. You need to adjust any of the column widths by dragging the right edge of the column border. • Also displayed are the following columns: • wetExp: wet exposure, hours • dryExp: dry exposure, hours • missedExp: missed exposure, hours • Cycles: the number of times the collector opened and closed • Repeat 13-16, if necessary: If more than one collector are connected to the raingage, you can close this window (after recording the values) and enter sample start and end times for the sample from the other collector. Drag this border to adjust the date column, if necessary Drag here to scroll left and right, if necessary • Exposure Definitions and Notes • Wet exposure: The time the collector was open and the optical sensor indicated that precipitation was occurring • Dry exposure: The time the collector was open, but the optical sensor indicated that precipitation was not occurring, and the collector should have remained closed. A sample with total dry exposure times exceeding 6 hours may be flagged as undefined and disqualified. • Missed exposure: The time the collector was closed, but the optical sensor indicated that precipitation was occurring, and the collector should have been opened. • A fourth possible state is not monitored or reported. This is when the collector is open and no precipitation is falling. • A small amount of dry exposure and missed exposure is inevitable, due to the differences between the optical and grid sensors. In certain conditions such as dry blowing snow, extensive periods of dry exposure will be recorded. This is also due to equipment limitations, and do not automatically invalidate a sample.

  10. Downloading from a NADP Raingage • Check the datalogger clock: Change to the Time page. Click the Check Time button and wait for a response. Any difference between the datalogger and PDA clocks will shows in the Difference text box. If it is not zero, click set time to update the datalogger clock. • Scroll if needed: Not all of the data can be displayed in the window, so scroll bars are provided at the bottom and possibly the right side of the window. You need to adjust any of the column widths by dragging the right edge of the column border. • Also displayed are the following columns: • wetExp: wet exposure, hours • dryExp: dry exposure, hours • missedExp: missed exposure, hours • Cycles: the number of times the collector opened and closed • Repeat 13-16, if necessary: If more than one collector are connected to the raingage, you can close this window (after recording the values) and enter sample start and end times for the sample from the other collector.

  11. Transmitting data • If the electronic gauge is your only NADP rain gauge, record the daily precipitation values from the PDA on the field form. Specify in the notes section of the field form that the daily values are from an electronic gauge. We are asking some sites to continue operating their Belfort raingage for a year, so we can investigate possible data biases introduced by the equipment change. If you are one of these sites, please record the Belfort values on your field form. • To transmit the electronic data, Connect your PDA to your desktop computer using the sync cable. On your desktop, click on My Computer, and then on Mobile Device. This will display the files in the My Documents folder of the PDA. Two files with data are created each time you download. One file will have a .txt extension, and the other will have a .xml extension. The first part of the name will be identical, and will contain your NADP siteid, the date and the time. For example, if I download from IL11 on Sept 3, 2006 at 10:00 am, the filenames will be: • IL1120060903T1000.txt • IL1120060903T1000.xml You can drag these files to the Archive directory that you created during Activesyns setup. • Each time you download, please email both of these files to me at blarson@uiuc.edu. In your email, please write the start and end dates and times for the sample. Emailing the data is just a temporary measure until we complete a desktop application that will automate this process. • There will be other files in the folder, such as dbschemal.xsd and rgdata.txt. These are temporary data files used on the PDA, and are overwritten each time you download. You can leave these files alone, and do not need to transmit them. Misc. Notes • The Util tab includes a utility to check the time of the gauge’s clock, and to synchronize the gauge's clock with the time of the PDA. The datalogger should be kept on Standard Time. If your PDA is on Daylight Savings Time, you can compensate for this by entering an offset value of 60. • You should not need to manually adjust the time of the PDA. Each time to connect the PDA to your desktop computer, the ActiveSync software will synchronize the PDA’s clock to the time of the desktop computer. • If you NADP Raingage Download Procedure

The Today page is what is shown on the PDA when no programs windows are visible. It is similar to the desktop on your PC. • You interact with the PDA by softly tapping on the touch-sensitive screen with the stylus. Tapping the screen is similar to clicking with a mouse. There are three types of taps: • Single tap: Tap once. • Double tap: Tap twice in rapid succession • Tap and hold: Press the stylus to an object on the screen and hold it there for a few seconds. If the screen object has a context menu, a menu of choices will appear. This is similar to right-clicking with a mouse. • In almost every situation, you will only use the single tap method. If you are required to use the double tap or tap and hold methods, we will point that out.
