The meteorological sensors were installed above the flat concrete roof of El Verde Field Station (elevation: 350 m asl). The building is in an approx. 0.3 ha clearing in a forest approx. 20 m tall. Data were processed and temporarily stored in a Campbell 21X data logger on-site. The station was initiated after the September 1989 hurricane. As this station was installed 3 meters above a concrete rooftop in a forest clearing, dry air temperatures during daylight hours are higher than those that would be measured in the adjacent forest. The USGS maintains a nearby (100 m away) station on a 20 m tower (since 1992). An additional station for temperature and humidity measurements in the forest understory was added in 1997. Additional measurements of daily rainfall and maximum and minimum air temperatures for this site since 1975 exist on separate files.
