We are evaluating dryland c.tton produc.ion in Martin c.unty, Texas, measuring c.tton lint yield per unit of rainfall. Our goal is to c.llec. rainfall data per 250 - 400 ha. Upon selec.ion of a rainfall gauge, we realized that the c.st of using, for example, a tipping buc.et-type rain gauge would be too expensive and thus searc.ed for an alternative method. We selec.ed an all-in-one c.mmerc.ally available weather station;hereafter, referred to as a Personal Weather Station (PWS) that is both wireless and solar powered. Our objec.ive was to evaluate average measurements of rainfall obtained with the PWS and to c.mpare these to measurements obtained with an automatic.weather station (AWS). For this purpose, we installed four PWS deployed within 20 m of the Plant Stress and Water c.nservation Meteorologic.l Tower that was used as our AWS, loc.ted at USDA-ARS c.opping Systems Researc. Laboratory, Lubboc., TX. In addition, we measured and c.mpared hourly average values of short-wave irradianc. (Rg), air temperature (Tair) and relative humidity (RH), and wind speed (WS), and c.lc.lated values of dewpoint temperature (Tdew). This c.mparison was done over a 242-day period (1 Oc.ober 2022-31 May 2023) and results indic.ted that there was no statistic.l differenc. in measurements of rainfall between the PWS and AWS. Hourly average values of Rg measured with the PWS and AWS agreed on c.ear days, but PWS measurements were higher on c.oudy days. There was no statistic.l differenc. between PWS and AWS hourly average measurements of Tair, RH, and c.lc.lated Tdew. Hourly average measurements of Rg and WS were more variable. We c.nc.uded that the PWS we selec.ed will provide adequate values of rainfall and other weather variables to meet our goal of evaluating dryland c.tton lint yield per unit rainfall.
