NASA presents at American Meteorological Society annual meeting

NASA researchers will present findings on a variety of Earth science topics at the American Meteorological Society 86th Annual Meeting Jan. 29 - Feb. 3 at the Georgia World Congress Center, Atlanta.

THE STUDY OF OZONE VARIATIONS IN THE LAS VEGAS METROPOLITAN AREA BY USING REMOTE SENSING INFORMATION AND GROUND OBSERVATIONS
TIME: Mon., Jan. 30, 10:00 a.m. EST, Room A316
SESSION: 1.5
The Las Vegas area experienced rapid urban growth in the past fifty years. In this talk, the long-term observations of urban development derived from satellite remote-sensing data, including the NASA / U.S. Geological Survey Landsat satellite, is used to explore urban land use and land cover impacts on low-level ozone concentrations and distributions.

THE POTENTIAL OF HIGH PERFORMANCE, REGIONAL TOTAL LIGHTNING NETWORKS AND ENHANCED DISPLAY PRODUCTS FOR PUBLIC SAFETY AND BROADCAST METEOROLOGY APPLICATIONS
TIME: Mon., Jan. 30, 11:45 a.m. EST, Room A307
SESSION: 2.4
Built upon technology first developed at NASA's Kennedy Space Center, Kennedy Space Center, Fla., Vaisala, Inc.,Houston, has been operating a regional lightning demonstration network in the Dallas-Fort Worth area since 2001. This talk will discuss how the network detects lightning flashes that are over 60 miles long. These flashes pose a significant public safety hazard since they often produce cloud-to-ground flashes along their path.

WARM SEASON GULF STREAM LIGHTNING: CONVECTIVE STRUCTURE AND FORCING
TIME: Tues., Jan. 31, 9:45 - 11:00 a.m. EST, Exhibit Hall A2
SESSION: Poster Session 2.10
NASA Scientist Walter Petersen used data from NASA's Tropical Rainfall Measuring Mission (TRMM) satellite and Moderate Resolution Imaging Spectroradiometer (MODIS) instrument to examine how aerosols and cloud properties produce a favorable environment for thunderstorm and lightning development over the Gulf Stream and eastern U.S.

HOW MUCH OF THE INTERANNUAL-TO-DECADAL FLUCTUATIONS OF THE INDIAN OCEAN SEA-LEVEL IS DUE TO ATMOSPHERIC FORCING AND TO CONNECTIONS WITH OTHER OCEANS?
TIME: Tues., Jan. 31, 9:45 a.m. EST, Exhibit Hall A2
SESSION: P3.1
In this workshop, researchers present the results of a 25-year study of sea-level variations in the Indian Ocean and how much of the variation can be attributed to wind fluctuations, internal ocean and atmospheric processes, and the movement of water between the Indian Ocean and the Tropical Pacific.

A MULTI-DECADAL POLAR CLIMATE RECORD FROM RADAR SCATTEROMETER DATA: THE SCATTEROMETER CLIMATE RECORD PATHFINDER PROJECT
TIME: Tues., Jan. 31, 9:45 a.m. EST, Exhibit Hall A2
SESSION: P2.10
Radar scatterometers were originally designed to measure near-surface winds from space, but they are also providing new insights into long-term changes of polar sea ice and the land surface. A long data record enables extensive studies of seasonal and interannual variability, as well as surface changes related to climate change. In this presentation, NASA-sponsored Scatterometer Climate Record Pathfinder data are used in several polar climate studies, including long-term sea ice extent and Antarctic tabular iceberg counts.

SUBSEASONAL ORGANIZATION OF OCEAN CHLOROPHYLL: PROSPECTS FOR PREDICTION BASED ON THE MADDEN-JULIAN OSCILLATION
TIME: Thurs., Feb. 2, 1:30 p.m. EST, Room A309
SESSION: 10.8
This presentation will show how the Madden-Julian Oscillation -- a 40- to 50-day pattern of variations in wind, sea surface temperature, cloudiness and rainfall in the tropics -- produces a significant basin-wide influence on the distribution of chlorophyll in the tropical Indo-Pacific. These results, in conjunction with recent studies indicating the oscillation may be predictable 2-3 weeks in advance, have important potential ramifications for the commercial fishing industry.

GLOBAL DISTRIBUTIONS OF THUNDERSTORMS BASED ON 7+ YEARS OF TRMM
TIME: Tues., Jan. 31, 2:30 p.m. EST, Room A307
SESSION: 5.3
TRMM has observed more than a quarter of a million thunderstorms since its launch in late 1997 and allows examination of many unique characteristics of these storms. In this talk, NASA's Daniel Cecil will discuss how the mission provides increasingly robust statistics, useful in analysis of thunderstorm distributions on seasonal and regional scales.

COMPARISON OF UNIFIED LAND USE AND LAND COVER DATASETS FOR URBAN SCALE MODELING OF METEOROLOGY, EMISSIONS, AND AIR QUALITY IN THE HOUSTON-GALVESTON AREA
TIME: Wed., Feb. 1, 11:30 a.m. EST, Room A316
SESSION: 5.11
This session will discuss advanced computer modeling techniques and their air quality and environmental applications in urban areas, including Houston. These new methods require a wealth of appropriate land use and land cover data, combined with Landsat satellite data.

AIR QUALITY, POPULATION AND ENERGY USAGE OVER GLOBAL MEGA-CITIES
TIME: Wed., Feb. 1, 2:30 p.m. EST, Exhibit Hall A2
SESSION: Poster Session 3.10
In this session, the influence of aerosols on urban air quality, human health and their role in atmospheric processes is discussed. By using aerosol observations from MODIS on NASA's Terra and Aqua satellites, preliminary results from research conducted over 100 large cities show a link between human population and air quality conditions.

MERGING AMSR-E HYDROMETEOR DATA WITH COASTAL RADAR DATA FOR SHORT-TERM HIGH-RESOLUTION FORECASTS OF HURRICANE IVAN
TIME: Thurs., Feb. 2, 9:45 a.m. EST, Exhibit Hall A2
SESSION: Poster Session P5.7
This session will examine how microwave data on hydrometeors from polar-orbiting satellites, including NASA's Advanced Microwave Scanning Radiometer-EOS, can be merged with traditional radar data to provide additional information about the evolution of hurricane rain bands during landfall, essential for improved warnings and preparedness activities.
