STAR 2008 News & Events

Menghua Wang's Ocean Color Work Featured on NASA Remote Sensing Site

photo of Menghua WangRecently, NASA's Earth System Science Data and Services group included an article on Menghua Wang's ocean color work in their publication Sensing Our Planet: NASA Earth Science Research. The article, entitled Cleaner Water From Space details Wang's work using the MODIS satellite sensor to detect, predict, and mitigate dangerous algal blooms in large bodies of water.

From the article:

Wang sees a key role for near-real-time space observations of lake water in the Taihu area and in other regions trying to manage increasingly pressured water resources. Wang said, "An image series like this will be very useful for local officials in the management of water quality. We will know what's happening, and when it's happening, and can give timely information to local governments for water quality."

The NASA publication is available on the web, via PDF, and in hard copy.

 

Felix Kogan Wins Commerce Gold Medal Award for Scientific/Engineering Achievement

image of vegetative health map from Felix Kogan's award winning projectDecember 2, 2008 - Felix Kogan recently received a Gold Medal Award from the U.S. Department of Commerce at the 60th Annual Honor Awards Ceremony on November 18, 2008. He was honored for his work developing space-based, worldwide drought early warning and vegetative health monitoring systems and transferring the technology to users in more than ten nations. This is the first operational use of NOAA's satellite instruments for monitoring vegetative health and correctly portraying drought onset and extent and an innovative use of a current NOAA Advanced Very High Resolution Radiometer (AVHRR) sensor. The system has been used to successfully monitor drought and affect agriculture and livestock policy in the U.S., Kazakhstan, and Georgia (Caucasus). See the website demonstrating his work here.

Workshop on Achieving Satellite Instrument Calibration for Climate Change (ASIC3)

For the most part, satellite observations of climate are not sufficiently accurate to establish a climate record that is indisputable and hence capable of determining at what rate the climate is changing. Furthermore, they are insufficient for establishing a baseline for testing long term trend predictions of climate models. The reasons for this state of affairs are many, but can be summed up in one all-encompassing statement: NOAAs operational satellite systems have been focused on short term weather observations, and NASA's research satellite systems have not had the long term continuity needed for monitoring climate change. As a result, highly accurate observations of decadal scale climate trends are generally lacking. The Workshop on Achieving Satellite Instrument Calibration for Climate Change (ASIC3), sponsored by NIST, NASA, NOAA, NPOESS-IPO, and Space Dynamics Laboratory of Utah State University, was organized to discuss the scientific issues involved and develop recommendations to improve the situation. The Workshop brought together experts in satellite instrument calibration, metrology scientists from the U.S. and U.K. national standards institutes, remote sensing specialists, and climate data analysts. STAR has been responsible for editing and preparing the Workshop Report, which has contributions from 29 scientists, and will publish the printed hard copy version.

Figure 12 from the report: Special Sensor Microwave Imager Sounder (SSMIS) observations compared to modeled background data illustrating bias and residual errorsTwo overarching recommendations were developed at the workshop. The first calls for a set of satellite benchmark missions to create irrefutable records and calibrate other satellite sensors. This is a new paradigm for measuring long-term global climate change. The basic concept is to place in space a series of highly accurate instruments, traceable to International Standards (SI), to measure with fine spectral resolution the energy reflected and emitted by the Earth. These instruments would not only provide reliable long- term records in their own right, but would also serve as a reference standard in space to calibrate other environmental satellite sensors. This recommendation also calls for maintaining continuous, overlapping missions for sea level, solar irradiance, and Earth radiation budget. The second overarching recommendation calls for establishing a U.S. National Center for Calibration (NCC). The NCC would bring together NOAA's expertise in operational missions and calibration/intercalibration of operational instruments, NIST's leadership in measurement science and standards, and NASA's capabilities in research missions and advanced calibration techniques.

Noteworthy STAR contributors to this workshop and its report include: Mitch Goldberg, Fuzhong Weng, and Changyong Cao were Lead Authors of three chapters; Larry Flynn was a contributing author, George Ohring edited the report, and Jerry Sullivan was a reviewer. Mary Kicza was the Keynote Speaker at the Workshop and Al Powell gave an invited talk on NOAA's calibration activities.

Clouds from AVHRR Extended Project (CLAVR-x)
Launches New Google Earth Site Serving STAR-Generated AVHRR Imagery

Google Earth users can now access the most recent high-quality satellite images generated at the University of Wisconsin-Madison's Space Science and Engineering Center (SSEC). The image of Google Earth AVHRR data Clouds from AVHRR Extended Project (CLAVR-x) is now using Google Earth to display false-color imagery. Currently, the site shows a pseudo true-color image which uses the AVHRR's 0.63, 0.86 and 10.8 micron channels to simulate what the eye would see from space. In the future, this site will show other false-color images to highlight cloud and surface properties as well imaging derived products. The global coverage of the images will increase when a new data server comes on line next year. The generation of the Google Earth images was done by Amato Evan at UW/CIMSS and Andy Heidinger at STAR/CoRP/ASPB with funding support from NOAA/NESDIS/STAR.

The Advanced Very High Resolution Radiometer (AVHRR) flies on the NOAA POES and EUMETSAT METOP series of polar orbiting satellites. The METOP/AVHRR provides global coverage with a resolution of 1 km. Data with a spatial resolution of 1 km is only available from the NOAA POES instruments when recorded by a direct broadcast station. We are using data from NOAA CLASS and this provides direct-broadcast data from several sites in the conterminous USA as well as Australia, Alaska and Hawaii. The site is updated every time a new data-set is found.

Special thanks to Andy Heidinger, CoRP/ASPB, and Amato Evan and UW for their work on this project.

Cheng-Zhi Zou

Dr. Zou is honored for developing an innovative and unique satellite instrument intercalibration technique, which allowed data from several NOAA satellites to be merged into a single consistent, long-term, climate-quality record. He analyzed this 25-year record to determine the global trends in atmospheric temperature. His result, a global temperature increase of 0.20 degrees C per decade, is consistent with trends observed from surface weather stations. His work adds substantially to the robustness of observed atmospheric temperature trends.

STAR Scientist Eric Leuliette Contributing Author of Chapter in Nobel-winning IPCC Report

photo of Eric LeulietteDr. Leuliette has been a research oceanographer with STAR in the Laboratory for Satellite Altimetry since January 2007. He came to NESDIS/STAR from the Colorado Center for Astrodynamics Research at the University of Colorado, where he was an assistant research professor in the Department of Aerospace Sciences and Engineering. He was recently recognized by NESDIS Administrator Mary Kicza along with 13 other NESDIS scientists for his contribution to the Intergovernmental Panel on Climate Change (IPCC) reports. IPCC was awarded the 2007 Nobel Peace Prize along with former Vice President Al Gore "for their efforts to build up and disseminate greater knowledge about man-made climate change, and to lay the foundations for the measures that are needed to counteract such change".

As a member of Working Group 1 of the IPCC, Eric was a contributing author and reviewer for the chapter "Observations: Oceanic Climate Change and Sea Level" of the IPCC's Fourth Assessment Report Climate Change 2007: the Physical Science Basis. Eric contributed the latest sea level rise estimates from satellite altimetry to the report. The chapter Dr. Leuliette contributed to and reviewed is available at: http://www.ipcc.ch/publications_and_data/publications_ipcc_fourth_assessment_report_wg1_report_the_physical_science_basis.htm.

The IPCC was established by the World Meteorological Organization (WMO) and the United Nations Environment Programme (UNEP) to assess scientific, technical and socio-economic information relevant for the understanding of climate change, its potential impacts and options for adaptation and mitigation. The IPCC report also provides a list of all of the contributors (Annex II, pages 954-979): http://www.ipcc.ch/publications_and_data/ar4/wg1/en/annexessannex-ii.html. More details about the IPCC and the Nobel Prize are on its official web site: http://www.ipcc.ch/.
