TITLE. National Atmospheric Deposition Program.
ABSTRACT. Two NADP sites, located at 2524 m elevation in upper montane forest
(Sugarloaf = CO94) and 3525 m in elevation and in alpine tundra (Niwot Ridge
Saddle = CO02), collected precipitation samples on a weekly basis. These were
analyzed for pH, conductivity, anions (Cl-, SO4--, NO3-), and cations (Ca++,
Mg++, K+, Na+, NH4+, H+) at the Central Analytical Laboratory in Champaign, IL.
INVESTIGATOR. Mark Losleben, INSTAAR, CB 450, University of Colorado, Boulder,
CO, 80309-0450, (303) 492-8841, markl@culter.colorado.edu.
VARIABLES. pH, conductivity, Cl-, SO4--, NO3-, Ca++, Mg++, K+, Na+, NH4+,
H+.
KEYWORDS. acidic, anions (Cl-, SO4--, NO3-), cations (Ca++, Mg++, K+, Na+, NH4+, H+), conductivity, dry deposition, pH, pollution, precipitation, wet deposition, Biogeochemistry, Atmospheric Inputs, disturbance.
LOCATION. Study sites were the Saddle (COO2) and Sugarloaf (CO94). Samples
are stored at Central Analytical laboratory, Champaign, IL. Original data
are available via ftp at sporobolus@nrel.colostate.edu.
TIMING. 5 June 1984, ongoing, weekly.

COMMENTS. Data in electronic form are available via anonymous ftp and via
the World Wide Web from the Natural Resource Ecology Laboratory in Fort
Collins, CO. The data in this location are the most up-to-date at any given
time and may include changes to older hard-copy reports. Therefore, the
data are not kept in this file. See the "data" section below for instructions
on accessing the data.

are already contained in this file, include the following
acknowledgment (in addition to an acknowledgment of the investigator)
in any published use of these data: "Logistical support

Research project (NSF DEB 0423662) and the Mountain Research Station

The data contained in these files have many sources. Generally,
data collected prior to 1993 would have been subjected to quality
control standards imposed by the investigator. Data after 1992
were likely to have been manually entered and/or processed in the
NWT LTER central data management laboratory. Detailed information
on the quality control protocols and programs associated with any
data routed through the NWT LTER data management laboratory will
be supplied upon request. The user of these data should be aware
that, while efforts have been taken to ensure that these data are
of the highest quality, there is no guarantee of perfection for
the data contained herein and the possibility of errors exists.
If you encounter questionable data, please contact the NWT LTER
data manager (todda@culter.colorado.edu; (303) 492-4771) so that
the data can be corrected or qualified. Thus, these data should
be considered dynamic in that past data may be modified and future
data will be appended.
