Boundary layer cloud variability using long-term measurements at two Atmospheric Radiation Measurement (ARM) observatories in the high and midlatitudes
Abstract
The feedback of clouds to the climate system continues to challenge our ability to accurately simulate the Earth's response to a warming climate. The influence of changes in aerosols and the large-scale environment on cloud variability can be amplified in sensitive climate regimes, such as the high latitudes. Long-term observations of clouds, aerosols, radiation, and atmospheric state are key to understanding the variability and changes in cloud radiative forcing on various time scales. We will examine the variability of these parameters at two Atmospheric Radiation Measurement (ARM) observatories located in the North Slope of Alaska and Southern Great Plains regions of the United States, which have over 20-yr of ground-based observations at each location. Changes in the boundary layer cloud radiative forcing and diurnal cycle will be examined in these two diverse climate regimes.
