Sagehen’s data is the result of a significant investment of resources over many decades. The station makes its data available free of charge with the provision that users will help us stay in business by:
- Complying with station use requirements— including proper publication credit to the station & to the data owners!
- Complying with our “Fair-Use” policy (see below);
- Submitting a reserve use application.
“Fair-Use” Policy for Sagehen data:
Kindly inform the appropriate Principal Investigators of how you are using site data and of any publication plans. If the Principal Investigators feel that they should be acknowledged or offered participation as authors, they will let you know and we assume that an agreement on such matters will be reached prior to publishing and/or use of the data for publication. If your work directly competes with the Principal Investigator’s analysis they may ask that they have the opportunity to submit a manuscript before you submit the one that uses their data. In addition, when publishing, please acknowledge the agency(s) that supported the research (including Sagehen Creek Field Station).
Obnoxiously, data links are constantly changing. If you find a broken link on this page AND locate an alternate source for the data, please let us know.
Major partners: University of Nevada – Reno, Desert Research Institute, James Kirchner – ETH, National Forest Foundation, Sierra Nevada Conservancy, US Geological Survey, Tahoe National Forest, UC Natural Reserve System.

Weather RADARHistorical NEXRAD (Next Generation Weather Radar system) weather radar data for the U.S. can be downloaded from the NOAA National Climatic Data Center. Map of radar station locations. Clicking on any of the stations brings up the station page, which has a link to the coverage map for that station. Reno (KRGX) or perhaps the Beale (KBBX) or Sacramento (KDAX) radars would probably be best for Sagehen. Up to 24 hours of data can be ordered from, each page. Clicking on ‘Create Graph’ provides a diagram showing the switches back and forth between ‘precipitation’ and ‘clear-weather’ modes each day; and then data can be ordered from this page. Enter your e-mail address and you will be sent an e-mail containing your HAS (HDSS Access System) Job Number. This may take a few minutes, or a few hours, to arrive. To order longer spells of data, go directly to the HAS page. The data can be displayed graphically, direct from the HAS servers, by NOAA’s Weather and Climate Toolkit. Although it is a beta version, it was recommended to me as the one to use for the high-resolution NEXRAD level II data by John Kobar and Steve Ansari at NOAA. It needs your computer to have Java 5 or later. Start the Weather and Climate Toolkit and the window for downloading data may appear automatically, but if not, it’s on the data menu, under ‘Load Data’. The NCDC tab allows you to enter a HAS job number. Press ‘List Files’ and you can select one or more from the remote server. It’s possible to select them all and press ‘Animate’ to, well, produce an animation, but it may take 40 minutes or an hour before the animation is ready. There are around 200 images for a 24-hour period. For lower resolution radar data, there is the Java NEXRAD viewer. There are other options, which are explained, starting with the first of the links above. |

National Atmospheric Deposition Program (NADP NTN Sagehen) data from our East Meadow (since November, 2001). The National Atmospheric Deposition Program (NADP) maintains a refrigerated archive of precipitation samples from the National Trends Network (NTN). NTN archive samples are filtered, stored in 60-mL polyethylene bottles at 4 deg. C, and are retained for five years. Archive samples are made available to interested researchers upon request after the specified retention period. The full NADP archive sample policy is posted here. If you would like to request NADP archive samples or have further questions, please contact Chris Lehmann at clehmann@illinois.edu or call 217-265-8512. Requesters pay the nominal cost of preparing and shipping the samples; a cost estimate will be provided before samples are shipped.

BIOLOGICAL INVENTORIES (SPECIES LISTS)
|
The Station has working species lists for the Sagehen Creek basin. Live biotic observations and crowd-sourced identification data updates these lists regularly since 2012 (sporadic observations from as early as the 1950’s). Completeness of lists varies, with plants receiving the bulk of the work to keep current. See referenced publications on each taxa list for more detailed information regarding occurrence and distribution. See especially the sources and papers below:
