For many years, the work of the so called “Jungle Reserach Group” has been closely linked with field observational boundary layer meteorology. Beginning in 1974 with GATE, it has been participating in a series of field experiments. The main research focus of this effort has been to make measurements of surface fluxes in remote environments. The measurements provide the foundation for basic and applied research in boundary layer meteorology.

In 1986 and 1988 we worked on surface turbulent exchange processes at the South Pole. Through the late eighties and early nineties, these included the NASA-sponsored ABLE projects, designed to understand the role of various globally significant ecosystems on greenhouse gas budgets. These projects resulted in trips to the Amazon rain forest, the Alaskan tundra and the boreal forest. Research in boreal systems continued in the period 1993-1996 with the micrometeorological flux measurement s in northern Manitoba in BOREAS.

Another ongoing project involves observations of the components of the radiation budget and characteristics of turbulent exchange at the forest-atmosphere interface at a research deciduous forest in central Massachusetts, where we collaborate with researchers from Harvard University. At the Harvard Forest field site, measurements have been conducted nearly continuously since August 1991. This ASRC research group has had a longstanding interaction with colleagues in Mexico (UNAM, Universidad Veracruzana) and in Brazil (Universidade de São Paulo, Universidade Federal de Santa Maria, RS).

We have participated in the Large-Scale Atmosphere-Biosphere Experiment in Amazonia (LBA). We have studied the role of weather on the curing of concrete. A collaborative study with the NY Department of Transportation and the National Weather Service to extract more useful information from newly-emerging roadside weather stations is just beginning. The projects have provided the impetus for many research papers.
