About These Blogs: The JPL Science & Technology Blogs are a way for our researchers and technical staff to give first-hand accounts of the activities that are going on at the Jet Propulsion Laboratory. A cross-section of our staff contribute posts about the tasks they are currently involved in for NASA and JPL. These blog posts are meant to discuss technical topics. Selected comments that are on-topic are published and are moderated.

Last week started off with welcoming my summer student, Ms. Huiwen Chuang, from the University of Michigan. She will work with me for 10 weeks this summer to analyze water vapor variability using AIRS and MLS data as well as IPCC model simulations. She spun up quickly and impressed me with the nice plots of AIRS water vapor time series for four ocean basins on the third day after her arrival in JPL. I expect a productive summer for her and me.

Prof. Richard Johnson visited JPL on June 18 and ...Read More on ''

An excitement happened last week was the meeting with Dr. Ed Weiler, associate administrator of the NASA Science Missions Directorate on Tuesday, June 9. I was asked by Dr. Diane Evans (JPL's Director for the Earth Science and Technology Directorate) and Dr. Randy Friedl (JPL’s Earth Science and Technology Directorate Chief Scientist) to give a short presentation to Dr. Ed Weiler about our recent work on CloudSat data analysis and comparison of observed and modeled cloud profiles (see last week’s ...Read More on ''

Just like many others on the lab, I joggle between several projects which involve the impacts of water vapor, clouds and aerosols on climate change. I work closely with my colleague in the Microwave Atmospheric Science group, Dr. Jonathan Jiang, on most of these projects. One of the topics we have been working on is to analyze observed cloud profiles and use them to evaluate cloud simulations in climate models. Our unique approach is to examine cloud profiles binned by large-scale state variables, ...Read More on ''

One of the profound scientific problems in the climate sciences is about building a realistic climate modeling (on computers) capability of clouds. If we can’t do this right, we can’t improve our future predictions of climate all that much. NASA makes an incredibly wide variety of ongoing measurements of clouds, temperature and humidity on a global basis from satellites. These measurements make it possible to observe what we should calculate in the climate forecasting models.

However, it is ...Read More on ''
