Abstract:

This data package contains locally verified monthly meteorological observations from a NOAA National Weather Service station located at the USDA Jornada Experimental Range headquarters in southern New Mexico, USA. Monthly summary data (based on daily observations) has been collected there by USDA staff since 1914 for minimum and maximum air temperature and daily accumulated precipitation using standard U.S. climatological service instrumentation and procedures. The included data were verified and transcribed directly from the original paper data sheets and have undergone quality control and assurance procedures different than those in place at NOAA. These data therefore differ from those directly downloadable from NOAA servers. Local verification and transcription of observations from the data sheets ceased in 1998 and data are now directly entered to the NOAA system. Therefore, this dataset is complete and will no longer be added to.

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 - daily and monthly data are available).

History and description

This data package contains locally verified monthly climate data collected at a weather station located at USDA Jornada Experimental Range (JER) Headquarters. This weather station is a National Weather Service (NWS) instrument and is part of the NOAA Global Historical Climate Network (GHCN). Daily climate observations have been collected by USDA JER staff and sent to the local National Weather Service office since 1914 until the present. These observations include minimum and maximum air temperature and daily accumulated precipitation made using standard U.S. climatological service instrumentation and recording procedures. The data sent to the local NWS office are subsequently quality controlled and assured and made available on NOAA servers.

Data here are monthly temperature and precipitation summaries that are based on observations stored in the local JER database. The JER database is based on data verified and entered from original paper data sheets stored at JER headquarters. Since this entry and verification process these 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 directly from NOAA servers. Most differences are in the precipitation observations, and these are documented in the history file (see "Additional documents" below).

All data from this station 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). There is another, automated NOAA weather station at JER Headquarters that began service in 2007 and has data available at the same portal (https://www.ncdc.noaa.gov/cdo-web/datasets/GHCND/stations/GHCND:USW00003074/detail).

Data evaluation by USDA and LTER staff

Local USDA JER and Jornada Basin LTER staff have noted that daily precipitation totals and temperatures at this station are total precip and min/max temps AT THE TIME OF MEASUREMENT BY THE OBSERVER. In a review of years 1914-1947 daily records, observer time fell between 1530 and 1900 with most observer times being between 1700 and 1800. Observer times changed to the morning between 0700 and 0900 at an unknown date after this and currently continue to be made in the morning. This local review also revealed discrepancies between official data at NOAA and the local datasheets that are most likely the result of incorrect data entry. These discrepancies are described in detail in the attached additional history document (see "Additional documents" below).

Additionally, it appears that some data sheets may have never been sent to, or posted by, the NOAA system. There are currently 35 monthly observations in this dataset that do not appear in the datasets that can be downloaded from NOAA. Over the 80+ year record in this dataset, there is therefore a discrepancy of 68.01 inches of precipitation. There are figures illustrating these and other discrepancies in the two datasets.

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 text file "NOAA_JERHQ_ws_monthly_his.txt" describes the procedures for identifying discrepancies between NOAA data and the data located at JER headquarters and the subsequent changes made in the included data file.

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

Related datasets

Pan evaporation data from the same location (also NWS) was collected from January 1956 through August 1979 and is found on EDI in package knb-lter-jrn.210379003.

Daily temperature and precipitation observations, data on which these summary data are presumably based, are found in EDI package knb-lter-jrn.210379001.

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.
