General study design
The Tromble Weir Watershed is a small experimental watershed
located in the East Bajada geomorphic unit of the Jornada Basin in
southern New Mexico, USA. We have instrumented this watershed,
which consists of a mixed Chihuahuan Desert shrubland, and have
on-going measurements and modeling studies of hydrological,
meteorological and phenological processes. The instrument network
consists of 15 soil moisture profiles arranged along hillslope
transects. A network of rain gauges and channel runoff flumes are
also deployed.
This data package contains data from four tipping bucket rain
gauges in the Tromble Watershed. One is located at the eddy
covariance tower and three others are distributed within the
watershed, co-located with three transects of instrumented soil
profiles.
Instruments and methods
Instruments used
Gauges R2, R3 and R4: Texas Instrument (TE525MM-L) tipping bucket
rain gauge with 9.66in orifice. Each tip represents 0.1mm.
Gauge R_tower: Texas Instrument (TE525-L) tipping bucket rain
gauge with 6in orifice. Each tip represents 0.254mm.
Methods (QC and data preparation)
First, erroneous values (IE: 7999) were queried and removed from
the raw data. Then data was checked again, to ensure all outliers
were removed. Next, the raw data was summed to one-minute
resolution and checked again for errors. Lastly, the one-minute
resolution precipitation data was synchronized with an already
created one-minute resolution timetable spanning the dates from
Oct 2016 to Dec 2019. Gaps between recorded precipitation events
were filled with zero values for no recorded precipitation.
Finally, to complete the record from 2010 to 2019 the new data
from 2016-2019 was appended to the end of the data spanning
2010-2016.
