Abstract:

Drought indices — Standardized Precipitation Evapotranspiration Index (SPEI) and the self-calibrating Palmer Drought Severity Index (scPDSI) —where derived from 9 United States Historical Climate Network (USHCN) stations on the Chihuahuan Desert in North America for this dataset. USHCN is a subset of the NOAA Cooperative Observer Program (COOP) Network, which consists of selected sites based on spatial coverages and completeness of data. Monthly precipitation depths, minimum, maximum and mean temperature were pulled from the dataset. These drought indices were derived using the SPEI package and scPDSI packages in R. Potential evapotranspiration was also calculated in R using the Thornthwaite method. All 9 sites are within the bounds of the Chihuahuan Desert in the state of New Mexico, with a single site (EL PASO) in the state of Texas.

Methods and protocols used in the collection of this data package

Description:

A total of nine United States Historical Climatology Network datasets were downloaded from NOAA’s National Centers for Environmental Information (NCEI) website. The 9 sites consist of the following stations across the Chihuahuan Desert in the United States: JORNADA, STATE UNIV, ORO GRANDE, TULLAROSA, EL PASO, GAGE, SOCORRO, ELEPHANT BUTTE DAM and LOS LUNAS. Data from 01-01-1911 to 12-31-2021 was used due to the consistency in each dataset.

Description:

A 12-month Standardized Precipitation Evapotranspiration Index (SPEI) was derived using precipitation depths and calculated potential evapotranspiration (PET) using the Thornthwaite method, using average temperature and latitude. The SPEI package in R was used for this derivation and was created by Santiago Begueria, Borja Latorre, Fergus Reig, and Sergio M. Vicente Serrano.
