ARM Cloudiness Intercomparison IOP 2003 Analysis: Cloud Base Height

Kassianov, E., Long, C., and Christy, J., Pacific Northwest National Laboratory
Fourteenth Atmospheric Radiation Measurement (ARM) Science Team Meeting

We have suggested a method for estimating Cloud Base Height (CBH) by using paired ground-based Total Sky Imagers (TSI) hemispherical observations (Kassianov and Long, 2003). Our results of the model-output inverse problem showed that, for broken clouds (single layer), moderately accurate CBH retrieval is possible. Both a TSI and a Hemispherical Sky Imager (HSI) were run simultaneously during the ARM Cloudiness Intercomparison IOP (Oklahoma, 2003). We use the data from these two instruments to evaluate the suggested method. We perform the CBH retrieval for a few fields of broken clouds (occurring at different altitudes) by using the suggested method. Then we compare the retrieval results (from TSI and HSI observations) with independent CBH estimations obtained with active remote sensing cloud layer (ARSCL) data. This CBH comparison will be presented as well as recommendations for the next ARM Cloudiness Intercomparison IOP. Kassianov, E., and C.
