Panorama from the top of Amazon Observation Tower
Detailed Description
Panorama (360 degree) view from the top of a 148-foot (45-meter) observation tower at the Amazon forest study site near Santarém, Brazil. The instrument on the tower, the USGS High Dynamic Range All-Sky Imaging System (HDR-ASIS), monitors atmospheric conditions and the solar radiation available for photosynthesis. Data from the system are being used by USGS Geographer Dennis Dye and his U.S., Brazilian and Australian collaborators to improve understanding of how photosynthesis in tropical forests responds to seasonal variations in climate.
