- The Integrated Surface Flux Facility (ISFF) is designed to study exchange
processes between the atmosphere and Earth's surface. This includes the direct
measurement of fluxes of momentum, sensible and latent heat, trace gases, and
radiation as well as standard atmospheric and surface variables. With multiple
sensors and data systems, measurements of horizontal and vertical gradients
also can be made. This facility, formed by integrating ATD's former Atmosphere
Surface Turbulent Exchange Research facility (ASTER) and Portable Automated
Mesonet (PAM III and Flux PAM) facilities, is quite flexible and has been used
in Arctic to desert conditions with sensor spacings from 1 m to 60 km (and
separations of 1000s of km are possible). Average statistics of all variables,
including the second-order moments needed to compute fluxes, are a standard
product of ISFF and are available in real-time for display. When possible,
every data sample is archived to allow processing using spectral, wavelet, or
conditional sampling methods. ISFF also supports the addition of user-supplied
sensors with digital or analog outputs at data rates up to 10,000 samples/s.
The ISFF is managed by ATD/RTF (formerly ATD/SSSF).
