MIRSL alum to head NASA Earth Science Division

Congratulations to MIRSL alumna Karen St. Germain, who has been selected to head NASA's Earth Science Division beginning June 2020.  Karen is moving to her new post from a senior position at NOAA's National Environmental Satellite Data and Informationn Service (NESDIS) where she has guided the ongoing development and deployment of NOAA’s major satellite programs.  More about her new appointment is available here

Karen completed her Ph.D. in 1993 at MIRSL under the guidance of Prof. Calvin Swift.  She often cites her experience at MIRSL, where she learned the full, end-to-end process of remote sensing, as a key to her success. "From establishing the science-based observation objectives, building the instruments, collecting the measurements in the field, developing the algorithms, processing the data and validating the results, MIRSL provides students a rare hands-on opportunity to learn the entire remote sensing process."

Congratulations, Karen!


Radar Testbed Launched

MIRSL students and engineers recently installed the second of two radar systems on the Orchard Hill tower.  Shown at right is the final phase of installing the Low Power Radar (LPR), a phased-array developed by Raytheon and currently on loan to UMass.  The LPR will be used to scan weather simultaneously with the UMaXX radar, which is a more conventional radar employing a mechanically-scanned antenna.  Observations by the two radars will be compared to a

Meet UMaXX

 MIRSL has just re-installed an X-band weather radar atop the tower on Orchard Hill on the UMass campus.  Formerly the platform for the CASA Engineering Research Center's prototype radar, the tower now houses the UMass eXperimental X-band radar (UMaXX).  UMaXX will be used for weather observations and as a reference radar for polarimetric studies with a phased-array radar on loan to UMass from Raytheon under research funded by the National

MIRSL/Raytheon Collaborate on Phased Array Weather Radar

MIRSL is collaborating with Raytheon in the advancement of phased-array radar technology for weather applications.  Pictured at right is the "Low Power Radar," an X-band, dual-polarized, phased-array radar developed by Raytheon employing low power solid-state radiating elements.  The array consists of 2560 individual antennas, each with arbitrary amplitude, phase, and polarization control.  With support from the National Science Foundation, MIRSL is adapting t

MIRSL Participates in new tornado study: VORTEX-SE

MIRSL is participating in the 2016 Verification of the Origin of Rotation in Tornadoes EXperiment -- Southeast (VORTEX-SE) sponsored by NOAA's National Severe Storms Laboratory.  During March and April 2016, MIRSL is deploying two mobile radar systems to northern Alabama to study the environment both leading up to and during severe weather outbreaks that can produce tornadoes.  MIRSL is partnering with the Purdue University Department of Earth Atmosphere and Planetary Sciences in this project. 

The two mobile radars include a polarimetric Doppler weather radar that volumetrically samples storms that pass within 60 km of its deployment site and a continuous frequency-modulated radar that collects vertical profiles of the atmospheric boundary layer throughout the experiment period.  Further detail on the radar instrumentation is available here.  Current and past radar observations for VORTEX-SE are available here.

Two Student Paper Prize Winners at 2016 AMS Annual Meeting

Two students won best paper awards during the recent 96th Annual Meeting of the American Meteorological Society in New Orleans, LA.  Sheila Werth presented "Evaluating Parameters for Species-Based Classification of Bird Radar Echoes for Wind Energy Site Assessment" in the Seventh Conference on Weather, Climate, Water and the New Energy Economy.  Her paper won Best Oral Presentation in the student paper competition.  Aditya Nagarajan presented "On Learning Patterns Between GPS Derived Precipitable water fields and Radar Reflectivity Fields” which won Second

Prof. Siqueira joins Science Definition Team on $600-Million NASA NISAR Mission

 Prof. Paul Siqueira is one of 15 scientists selected by NASA to serve on the Science Definition Team of a $600-million collaborative mission between NASA and the Indian Space Research Organization (ISRO). In a meeting in Toronto on September 30, NASA Administrator Charles Bolden and K. Radhakrishnan, chairman of ISRO, signed two documents to launch a NASA-ISRO satellite mission to observe Earth and establish a pathway for future joint missions to explore Mars.
