From February 1997 to January 1998, air and soil temperature was measured at 10 locations along a windward, elevation gradient in the Luquillo Experimental Forest (LEF) of Puerto Rico (Site Map). Soil temperature was measured at a depth of 15-20 cm at each site (Table 1). Air temperature was measured at 1.3 m above the soil surface. All sites, except the Sabana forest site (asf, ssf) were in clearings that received direct solar radiation (Table 1). The Sabana forest site was located beneath a closed canopy forest that was adjacent to the open canopy site (asa, ssa).
Air temperatures were measured with Optic StowAway temperature sensors. Soil temperature was measured with StowAway TidbiT XT temperature sensors. The manufacture of these sensors estimates the typical error of the air and soil sensors are +/- 0.2C and +/- 0.3C respectively. Temperature was measured every 6 minutes and averaged by hour and month (Tables 2 to 13).
