Abstract:In 2014, the National Aeronautics and Space Administration and the Japan Aerospace Exploration Agency launched the Global Precipitation Measurement satellite to observe and retrieve information about precipitation around the world. The satellite retrieval algorithms require several assumptions about the cloud in order to estimate the amount of precipitation that is occurring. The images shown here were observed by an aircraft flying 100 m/s in clouds above the Olympic Mountains in Washington State. Information from these images, and from other airborne probes, provide valuable data about clouds including the number and size of the crystals as well as the environmental conditions that are creating these crystals. My research uses this information to evaluate the assumptions of the algorithms and work to improve the estimates of precipitation. Once the algorithm assumptions are improved, the data can be used for forecasting weather systems, understanding the global water cycle and diagnosing how precipitation changes around the globe in a changing climate.
