With funding support from CPO's Climate Monitoring Program, Researchers at the Scripps Institute of Oceanography have published new research applying important "corrections" to two widely-used, long term satellite cloud data records (The International Satellite Cloud Climatology Project (ISCCP) dataset and the Pathfinder Atmospheres–Extended (PATMOS-x) dataset).
Because they are constructed from weather satellite measurements lacking long-term stability, ISCCP and PATMOS-x suffer from artifacts that can introduce "spurious" variability in the records over time, which can inhibit their use in cloud change studies.
In a new paper published in the Journal of Atmospheric and Oceanic Technology, lead author Joel Norris and colleagues discuss the need for and the methods used to make these corrections. The two new datasets are freely available and archived at the Research Data Archive at the National Center for Atmospheric Research, Computational and Information Systems Laboratory. http://dx.doi.org/10.5065/D62J68XR.
This project was the result of a grant from the Climate Monitoring program within COD to SIO.
