A41N:
Cloud Observations and Uncertainties I
Session ID#: 11009
Session Description:
Clouds play a significant role in Earth’s hydrological cycle and radiation budget. Representation of clouds in climate models remains as one of the largest uncertainties in predictions of future climate. Long-term cloud retrievals with accurate uncertainty estimates are necessary for improving cloud parameterizations within climate models.
Cloud properties can be retrieved using space- or ground-based remote sensors or directly from in situ aircraft probes. Studies have shown large differences of cloud properties among various methods, raising questions about the assumptions behind them and/or their representativeness. The uncertainties could come from the measurements themselves and retrieval algorithms applied downstream to them. To advance our understanding of clouds and their processes, it is crucial to understand and quantify the uncertainties associated with measurements and retrievals.
This session invites papers on cloud property 1) measurements or retrievals, 2) uncertainty analyses, and 3) implementation of realistic uncertainties on the measurements and retrievals.
