Biodiversity tipping bucket rain gauge data - By Event

Study number: 


Data set ID: 


Data Access: 


Dataset status: 


These data are collected to provide a measurement of rainfall at the Biodiversity site. They are detailed records providing a time stamp of month/day/year hour:minute:second for each tip of the tipping bucket rain gauge (equal to 0.1 mm of precipitation).

Data sources: 



Novalynx tipping bucket rain gage, model 6011. Novalynx Corporation rain gage pulse recorder, model 260-2107. Data are down loaded to a portable hand held data transfer unit. These data are then downloaded to a computer using Novalynx software.

1. Field data collection procedure: Remove outer white metal cover of rain gauge. Connect long cord from DTU (data transfer unit) to rain gauge. Press button on top of DTU. (Instructions are also on front of DTU). Green light will flash when download is complete. Disconnect and replace cover. Follow instructions to download data in laboratory. ----------------------------------- 2. DTU to Computer transfer procedure: Instructions for use of rain gauge program Click on the Novalynx icon and wait for date prompt -the program will ask for confirmation of the date -if the date is correct, press ENTER when prompted -if the date is incorrect, type in the correct date, then press ENTER -the program will ask for confirmation of the time -if the time is correct, press ENTER when prompted -if the time is incorrect, type in the correct time, then press ENTER To download data from the DTU: -when asked to "Select Device to Integrate" press F2: Data Transfer Unit -when prompted, attach the short cord of the DTU to the serial cable(!) not to the serial port. Make sure the connection is very tight otherwise the data will not export properly. press ENTER *note-the DTU must be attached to the serial cable supplied with the rain gauge or the data will not download to the computer -when asked to "Make Your Selection" press F1: Automatically Process DTU Data -when asked "Do You Want Data Filename Prompting?" press N *note-this will automatically create a filename consisting of the DTU number and the date the data is downloaded. For example, if data is downloaded on 8 April, 1996, the file will read 21310408.d07. This file will be auto- matically saved to the A: drive. (!) A floppy disk must be in the A: drive for the data to be downloaded (!). -when asked to "Make Your Selection" press F10: Go To Main Menu To create an ASCII file: -at the main menu: -press F1: Analyse Recorder Data -press F5: Read Recorder Data From Disk -select the desired file -press F1: Display/Print/Export Raw Data -press F3: Export to Spreadsheet File -enter date as filename -for example, if the data is downloaded on 8 April, 1996, enter 040896 as the filename. *note-do NOT use slashes or hypens in the filename. Use the default extension (.PRN), this does not have to be typed in, but will be automatically incorporated into the filename by the program. -press F10 at each menu until you have exited the program -once at the c: prompt, save the file from the floppy disk to the hard drive ----------------------------------- 3. Database data and output to ASCII: Append ASCII file (generated in step 2 above) to FoxPro BD_PRECP.DBF file using standard FoxPro methodology. Output additions to BD_PRECP.DAT ASCII data file using standard FoxPro methodology.

Additional information: 

Biodiversity study site. From the stone pillars at the south entrance of the Jornada Experimental Range (USDA), follow the road west approximately 4 miles to the first (wretched) gate on the right (north). Go through this gate approximately one quarter mile, parking spot is on west side of road under power lines. The Biodiversity site is on the right (east) side of the road across from the parking spot. The raingage is located about 5m south of Plot #46, which is due east of the parking spot, about 100m. The Biodiversity site is to the southeast of Summerford Mountain.
