The Envi Lab database records the results from the hydro-geochemical and meteorological research and sampling in Hopkins Memorial Forest (HMF). We monitor local weather and climate and help to provide students and faculty with these data for their class-based and long-term research projects.

We have been measuring precipitation and streamflow chemistry (Birch Brook watershed) on a biweekly or monthly basis since 1983. We have also monitored discharge (Q) and stream temperature since 1984 and 1994 respectively, at two sites in the Birch Brook.

Since 1983, we have recorded weather data at four stations located throughout HMF. Our main Weather Station measures air temperature, humidity, precipitation, wind speed/direction, sunlight, soil temperatures, and ground water levels and updates 10 minute intervals. We also have a 50-m MET tower collecting hourly wind speed and direction, plus temperature at the site since 2004. In addition, the data from our 7.2 kW photovoltaic array on the roof of Morley has been online in 2005.
