Technical Abstract: As a part of the Department of Energy Cloud and Land Surface Interaction Campaign (CLASIC) in June 2007, the land cover/land use was characteristized over the Atmospheric Radiation Measurement Southern Great Plains Testbed in Oklahoma throughout the month long field campaign. Excessive and persistent rainfall during the study confounding the process by introducing a significant amount of cloud cover during the campaign time frame (June 2007), which resulted in no satellite coverage during the study period. These conditions also produced extensive flooding in the Oklahoma region during June of 2007, limiting ground surveys and also impacting land management practices, particularly the harvesting of winter wheat. Using both the Advanced Wide Field Sensor (AWIFS) and the Landsat 5 Thematic Mapper sensor, a land cover and land use classification scheme was developed. A combination of pre and post campaign satellite overpasses and a priori knowledge on the dynamics of land cover in the Oklahoma region were used to produce land cover maps for various times of the year. From these maps, a logical decision tree was established to estimate the land cover during the campaign time frame. The final imagery is a moderately accurate depiction of the land cover during CLASIC, however, there is still some uncertainty on the exact dates of winter wheat harvest time in a particular field due to the considerable cloud cover.
