203 – Diurnal Variation of Tropospheric Trace Gas Amounts and Aerosol Optical Characteristics
Principal Investigator(s): M. Tzortziou

The project involves the development of a new ground-based network of highly accurate spectrometer systems (Pandora and Cleo instruments, Fig 1) and the development, optimization and validation of remote-sensing retrieval algorithms for obtaining new measurements of aerosol optical characteristics and tropospheric trace gas amounts and vertical distribution (NO2, O3, SO2, H2O, HCHO). The resulting data provide a unique dataset for bounding tropospheric photochemical models, and studying the evolution of tropospheric ozone, NO2, other trace gases, and aerosols and their impacts on climate and air quality. Measurements are applied to improve interpretation of current satellite observations and assess more effective design and observing strategies for future NASA satellite missions.

ESSIC Sees Success with Maryland Day Display

Despite less than desirable weather, many people still turned out for Maryland Day, a campus wide open house event to promote the departments, organizations and activities around campus.

ESSIC’s display this year was situated on “Science and Tech Way,” with other science and math displays.

Andrew Negri, co-organizer of the event, said ESSIC had 25 volunteers helping out throughout the day, and the weather didn’t stop what he described as “very high traffic” to ESSIC’s …

DYNAMO success: MJO field campaign comes to a close

COLLEGE PARK, Md. – Since late 2011, ESSIC scientists have grown accustomed to seeing periodic updates always carrying a similar subject: DYNAMO news. Sent by CICS’s own Augustin Vintzileos, the e-mails signify the success of the Dynamics of the Madden-Julian Oscillation (DYNAMO) campaign, which started on October 1st, 2011 and came to a close March 31, 2012. In the 1970s, NCAR scientists Roland Madden and Paul Julian discovered what would later be called the Madden-Julian Oscillation …

Liang Releases CWFR Source Code

COLLEGE PARK, Md. – University of Maryland’s Earth System Science Interdisciplinary Center researcher Dr. Xin-Zhong Liang, also a professor in the CMNS-Atmospheric & Oceanic Science Department, released a regional climate model Fe. 17 called the Climate-Weather Research Forecasting Model (CWRF), a significant extension of the original Weather Research Forecasting Model (WRF). The model has been ten years in the making by Dr. Liang’s team in collaboration with NOAA and NCAR, and …

New yoga group meets at ESSIC

Don’t be surprised if you see a group of people walking in to a third floor wing at ESSIC with rolled up mats and donning exercise clothes.  They’re the ESSIC Tuesday yoga group, led by Hui Xu and a tape recording that talks them through their poses. Employees at the NOAA World Weather Building in Camp Springs, MD have been running a similar class for nine years, and will move in to a new M Square building later this summer. Even though the move means classes in a neighboring building …

ESSIC scientists participate in WCRP Conference

At the World Climate Research Programme (WCRP) Conference, Denver, CO, October 24-28, Robert Adler (ESSIC) was the session convener for “Inter-annual and Inter-decadal Variations and Trends in Global and Regional Precipitation and Their Relation to Temperature and Water Vapor Changes.” Omar Muller (ESSIC, advisor Hugo Berbery) won the Best Scientific Presentation award for students and early career scientists with the poster “Using ecosystem functional types as lower boundary conditions in …
