Climate, 25, 4699-4720. doi:10.1175/JCLI-D-11-00267.1. (Reprint, abstract.) The properties of clouds that may be observed by satellite instruments, such as optical thickness and cloud top pressure, are only loosely related to the way clouds are represented in models of the atmosphere. One way to bridge this gap is through "instrument simulators," diagnostic tools that map the model representation to synthetic observations so that differences between can be interpreted as model error. But simulators may themselves be restricted by limited information or by internal assumptions. This paper considers the extent to which instrument simulators are able to capture essential differences between MODIS and ISCCP, two similar but independent estimates of cloud properties. The authors review the measurements and algorithms underlying these two cloud climatologies, introduce a MODIS simulator, and detail data sets developed for comparison with global models using ISCCP and MODIS simulators. In nature MODIS observes less mid-level cloudiness than ISCCP, consistent with the different methods used to determine cloud top pressure; aspects of this difference are reproduced by the simulators. Differences in observed distributions of optical thickness, however, are not captured. The largest differences between can be traced to different approaches to partly-cloudy pixels, which MODIS excludes and ISCCP treats as homogeneous. These cover roughly 15% of the planet and account for most optically thinnest clouds. Instrument simulators can not reproduce these differences because there is no way to synthesize partly-cloudy pixels. Nonetheless, MODIS and ISCCP observation are consistent for all but the optically-thinnest clouds, and models can be robustly evaluated using instrument simulators by integrating over the robust subset of observations.
