Abstract: 

    This data set is comprised of daily precipitation totals, in inches, measured by Belfort
     Instruments weighing rain gauges at 58 locations on the Jornada Experimental Range.

    This data set is comprised of daily precipitation totals, in inches, measured by Belfort
     Instruments weighing rain gauges at 58 locations on the Jornada Experimental Range.
     Locations and the dates during which data were collected at them were generally project-oriented.
     See comment section (#20) for start and end dates for each location.

    Days on which data could not be obtained (due to equipment failure, user error, and/or
     other reasons) are flagged as missing within this dataset.  As of 31 December 2008 they
     comprised 1,270 of the total 291,465 records, which is less than 0.44% of the data set.

Methods: 

    All data were collected with Belfort Universal Precipitation Gauges, Series 5-780.
      (http://www.belfortinstrument.com/content/precipitation_s5780_5915.cfm accessed 27 October 2017)
    The weighing rain gauges have a collection bucket connected to a scale.  A pen attached to
     the scale records weight as a continuous line on a 7-day chart mounted on a rotating
     drum.  The drum makes one complete rotation per week.  Each week, a technician visits each
     gauge to empty the bucket, wind the drum's rotation mechanism and collect the chart and
     mount a new one.  Technical staff interpret the trace on the charts and record
     precipitation to the nearest hundredth inch of precipitation per day.  Each daily
     measurement for a given gauge comprises a record in this dataset.  Date were
     entered directly into Excel spreadsheets and later compiled with SAS.

    For some days on which data at a given location could not be obtained, the daily
     precipitation was estimated by interpolation from other nearby weighing rain gauges.
     These estimates are flagged in this dataset.  However, no standardized protocol was
     followed in calculating them.  The decision to calculate and enter them was at the
     discretion of the technical staff interpreting the datasheets of traces.  The general
     purpose of these estimates was to allow for more accurate calculations of annual
     precipitation.

    Five observations in this dataset are flagged as "trace" and have zeros in the precip
     column.  In these cases, the technical staff interpreting the charts saw evidence of
     precipitation that totaled less than 0.01 inches.  However, the "trace" designation
     was not assigned consistently when interpreting the charts for this dataset.

Additional information: 

 All coordinates are WGS84, UTM Zone 13N.  Note that some locations are estimated.  This
    information is also available as a shapefile (see #20).
