| Abstract | During the summer of 1989, the NAE Twin Otter Atmospheric Research Aircraft was flown in a special three week extension the NASA-sponsored First ISLSCPâ‚‚ Field Experiment (FIFE-89). Airborne measurements of the fluxes of heat, momentum, water vapour and carbon dioxide were made during 16 low-altitude flights over the FIFE project area in central Kansas. This report documents the Twin Otter operations in FIFE and includes details on the instrumentation, software, flight procedures, atmospheric conditions and analysis methods. Run-average data are presented for all 285 flux runs flown by the Twin Otter in FIFE-89. This report is intended to serve as a working reference for scientists utilizing Twin Otter data either directly or through the FIFE data archive at the NASA Goddard Space Flight Center. |
