Description :
The AA. analyze the temporal stability of soil moisture at the field and watershed scales in the Little Washita River Experimental Watershed (LWREW), as part of the remote sensing Cloud and Land Surface Interaction Campaign (CLASIC07) during June 2007 in south-central Oklahoma. The aims of this study were to : 1) determine temporally stable sites for surface and profile soil moisture in 4 fields within the LWREW under different land management practices and for various soil types; 2) determine the extent of correlation between surface soil moisture and profile soil moisture temporal stability analysis; and 3) analyze the temporal stability of soil moisture at the field and watershed scales to identify stations within the watershed, as well as locations within each field, that were representative of the mean areal soil moisture content. In addition, the AA. compared their findings with those from past studies in the watershed under much drier conditions.
