Abstract:

This data package contains locally verified monthly total pan evaporation data from a NOAA National Weather Service station located at the USDA Jornada Experimental Range headquarters in southern New Mexico, USA. The evaporation pan measurements commenced in 1953 and ended in 1979 when the instrument was decommissioned. Pan evaporation observations were made using standard U.S. climatological service instrumentation and procedures. The included data were verified and transcribed directly from records retrieved from NOAA in ~1995 and have since undergone quality control and assurance procedures different than those in place at NOAA. These data therefore differ from those directly downloadable from NOAA servers. There is no further data from this decommissioned instrument, so this dataset is now complete and data will no longer be updated here.

All observations from this weather station have also undergone NOAA QA/QC procedures and those data are available by accessing the Jornada Experimental Range, NM US GHCN station through the National Climatic Data Center portal (https://www.ncdc.noaa.gov/cdo-web/datasets/GSOM/stations/GHCND:USC00294426/detail - monthly pan evaporation data are available back to 1930, but there may be data issues prior to 1953).

History and description

This data package contains monthly evaporation observations collected at an evaporation pan instrument located at USDA Jornada Experimental Range (JER) Headquarters. The evaporation pan was a National Weather Service (NWS) instrument and is part of the NOAA Global Historical Climate Network (GHCN). Monthly observations of evaporation in inches of water were collected by USDA JER staff and sent to the local National Weather Service office from around 1953 until the instrument was decommissioned in 1979. These observations were made using standard U.S. climatological service instrumentation and recording procedures. The data sent to the local NWS office was subsequently quality controlled and assured and made available on NOAA servers.

This dataset contains monthly evaporation data that are based on observations stored in the JER database, which were ultimately derived from floppy disks obtained from a NOAA office in Maryland. Since this time, these JER data have undergone quality control and assurance procedures different than those in place at NOAA (see below), and the data therefore differ from what is available currently from NOAA servers. There are far fewer missing observations in this dataset than the NOAA dataset (see "Additional documents" below).

All data from this evaporation pan that have undergone NOAA QA/QC procedures are available by accessing the Jornada Experimental Range, NM US GHCN station through the National Climatic Data Center portal (https://www.ncdc.noaa.gov/cdo-web/datasets/GSOM/stations/GHCND:USC00294426/detail). Evaporation data going back to 1930 is retrievable from NOAA servers, but there appear to be data issues prior to 1953.

Data evaluation by USDA and LTER staff

Discrepancies between this data set and data now available from NOAA suggest that data entry errors or additional data filtering has occurred at NOAA. This resulted in a higher frequency of missing data in the data directly downloadable from NOAA servers. This data package remains to document those discrepancies, but is now considered complete and will not be updated in the future.

Additional documents

The attached history text file "NOAA_JERHQ_ws_panevap_his.txt" describes the procedures for identifying discrepancies between NOAA data and JER headquarters data and the subsequent changes made in the included data file.

The summary figures "local_vs_noaa_monthlyevap_diff.png" and "local_vs_noaa_cumulative_monthlyevap.png" plot the discrepancies between the local JER data and NOAA server data from the most recent data request.

Abstract:

The Jornada Basin Long-Term Ecological Research (LTER) program is part of a national network of long-term ecological research sites funded by the US National Science Foundation (NSF). The Jornada LTER program has been continuously funded since 1982 to develop general principles governing changes between grassland and shrubland ecosystems based on long-term data collected in the Chihuahuan Desert. We translate our findings to dryland ecosystems around the world, and forecast the dynamics of future ecosystem states in response to changing climate and land use.

JRN LTER is funded by the National Science Foundation under award DEB 2025166.
