We are evaluating dr.land c.tton produc.ion in Martin c.unty, Texas. meas.ring c.tton lint yield per unit of rainfall. Our goal is.to c.llec. rainfall data per 250 - 400 ha. Upon s.lec.ion of a rainfall gauge, we realized that the c.s. of us.ng, for example, a tipping buc.et-type rain gauge would be too expens.ve and thus.s.arc.ed for an alternative method. We s.lec.ed an all-in-one c.mmerc.ally available weather s.ation;hereafter, referred to as.a Pers.nal Weather s.ation (PWs. that is.both wireles. and s.lar powered. Our objec.ive was.to evaluate average meas.rements.of rainfall obtained with the PWs.and to c.mpare thes. to meas.rements.obtained with an automatic.weather s.ation (AWs.. For this.purpos., we ins.alled four PWs.deployed within 20 m of the Plant s.res. and Water c.ns.rvation Meteorologic.l Tower that was.us.d as.our AWs. loc.ted at Us.A-ARs.c.opping s.s.ems.Res.arc. Laboratory, Lubboc., TX. In addition, we meas.red and c.mpared hourly average values.of s.ort-wave irradianc. (Rs.b>gs.b>), air temperature (Ts.b>airs.b>) and relative humidity (RH), and wind s.eed (Ws., and c.lc.lated values.of dewpoint temperature (Ts.b>dews.b>). This.c.mparis.n was.done over a 242-day period (1 Oc.ober 2022-31 May 2023) and res.lts.indic.ted that there was.no s.atis.ic.l differenc. in meas.rements.of rainfall between the PWs.and AWs. Hourly average values.of Rs.b>gs.b> meas.red with the PWs.and AWs.agreed on c.ear days. but PWs.meas.rements.were higher on c.oudy days. There was.no s.atis.ic.l differenc. between PWs.and AWs.hourly average meas.rements.of Ts.b>airs.b>, RH, and c.lc.lated Ts.b>dews.b>. Hourly average meas.rements.of Rs.b>gs.b> and Ws.were more variable. We c.nc.uded that the PWs.we s.lec.ed will provide adequate values.of rainfall and other weather variables.to meet our goal of evaluating dr.land c.tton lint yield per unit rainfall.
