The data contained on this
site are freely available and we encourage others to use it.
kindly keep us informed of how
you are using our data and
of any publication plans. Please acknowledge the data source as
a citation, or in the
acknowledgments if the data
have not yet been published. If we feel that we should be
offered participation as
authors, we will let you
know and we assume that an agreement on such matters will be
reached prior to publishing the
data. If your work directly
competes with our analysis we may ask that we have the
opportunity to submit a manuscript
before you submit one that
uses unpublished data. These data may be updated or reprocessed
from time to time, and it
is your responsibility to
insure that your publication contains the most recent revision
of the data.
In order to maintain these
measurements we periodically need to demonstrate progress to our
sponsoring agencies. In
addition to informing us of your plans, we kindly request that you
help us by providing preprints and updates on
publication status.

Important note for people using precipitation data. The
precipitation time series in these files were collected with
unheated tipping bucket gauges; these gauges were not always
ideally positioned or maintained; and little effort has
gone into cleaning these P records. These records often
provide a qualitiative indicator of whether it was raining at
the time, but should not be used for quantitative estimates
of either short or long term water balance. Send mgoulden
an email if you're intersted in daily P time series for some or
all of the sites.
The main files are discontinuous and have not been gap filled or
filtered for calm conditions (u*). We routinely do this
using a Matlab program Flexible Filler: Allsites_flexible_fillerV4.m
Data Version: All files have been processed with our 3rd
generation set of code (v3)
Data Release: v3_3 (May 2015 or earlier), v3_7 (October 2018)
