AB: The interannual variability and long-term trends of cloud occurrence and cloud radiative effects are a topic of current interest given other global environmental changes that are ongoing. While satellite data are typically the measurement of choice to study this topic, the use of long term measurements from the ground are able to add significant information regarding regional cloud occurrence and cloud effect trends. The Atmospheric Radiation Measurement Program sponsored by the U.S. Dept. of Energy has operated active and passive remote sensors at their Southern Great Plains (SGP) facility for more than 8 years. We will explore this data set for any trends in cloud occurrence as a function of cloud type and examine the record for interannual variability in cloud properties and cloud radiative effect. We will propose that long term data of this type can provide important ground-truth for satellite based inferences of cloudiness trends.
