Soil and Air Temperatures During the Forest Ecosystem Dynamics - Multisensor Aircraft Campaign

Forest Ecosystem Dynamics Multisensor Airborne Campaign (FED MAC): Soil and Air Temperatures The Biospheric Sciences Branch (formerly Earth Resources Branch) within the Laboratory for Terrestrial Physics at NASA's Goddard Space Flight Center and associated University investigators are involved in a research program entitled Forest Ecosystem Dynamics (FED) which is fundamentally concerned with vegetation change of forest ecosystems at local to regional spatial scales (100 to 10,000 meters) and temporal scales ranging from monthly to decadal periods (10 to 100 years). The nature and extent of the impacts of these changes, as well as the feedbacks to global climate, may be addressed through modeling the interactions of the vegetation, soil, and energy components of the boreal ecosystem.

These data contain soil and air temperatures measured at the tower site (HF2) in the Howland Forest. The data represent hourly averages: year, Julian day, time, soil temperatures at 3.8, 7.6, 16.5, 21.6, 31.8, 62.2 cm depths, julian day, time, and air temperature above the canopy. All temperatures are in degrees C. The duplication of day and time is due to retrieving data from two data loggers with different methods of denoting midnight.

There are some hours with missing or invalid data that have been given 'dummy', out of range, values as place holders. These are soil temperatures for day 147, time 1200 and 1300, and air temperatures for days 173 through 176, for several hours.
