Dr. Dorothy Hall

Cryospheric scientist Dorothy Hall has been working with the intricacies of measuring snow and ice through satellite remote sensing for more than 40 years.
 
Snow keeps the earth cool by reflecting radiation from the sun before it can be absorbed by the earth. Tracking snow cover in polar regions allows scientists to observe changes in temperature, making it a good way to measure the scale and effects of climate change. 
 
“It’s interesting to be

JPSS-1 will kick off next era of polar satellites

NASA and NOAA will launch the JPSS-1 Satellite from California Tuesday, Nov. 14, the first of four next generation satellites which orbit pole to pole collecting global data on atmospheric conditions.   Polar satellites allow for high accuracy weather forecasting up to a week in advance, said NOAA’s Mitch Goldberg, the Joint Polar Satellite System (JPSS) chief scientist.   “All the major weather prediction centers throughout the world, they use our …

Petty, Boisvert co-authors of new Arctic winter warming study

ESSIC researchers Alek Petty and Linette Boisvert are co-authors of a new study that has determined that temperature peaks above minus 10 degrees Celsius are occurring more frequently during the arctic winter.  Titled “Increasing frequency and duration of Arctic winter warming events,” the study published in Geophysical Research Letters (GRL) has been featured by both the American Geophysical Union (AGU) and NASA’s Goddard Space Flight Center.  Although arctic …

Brunt, Petty quoted in Baltimore Sun

ESSIC researchers Alek Petty and Kelly Brunt were quoted in a Baltimore Sun article on the recent calving of the Larsen C ice shelf in Antarctica. The researchers were specifically asked if the event could be connected or attributed to global warming, but both scientists felt the calving was part of the normal ice shelf splintering and recovery processes that have occurred in the past and will continue in the future….

Petty study published in Earth Future, featured by NASA

ESSIC Post-doctoral Associate Alek Petty recently published a paper on forecasting summer Arctic sea ice. The paper, titled “Skillful spring forecasts of September Arctic sea ice extent using passive microwave sea ice observations,” was published in the American Geophysical Union’s Earth Future. In the study, Petty discusses the use of a new satellite-based forecasting model to better estimate Arctic Sea ice loss during the spring months. A NASA feature, which …

Brunt chats ice on the PBS Newshour

ESSIC Associate Research Scientist Kelly Brunt was interviewed March 8 during a segment of PBS Newshour. The feature expounds on the sectional disappearance of the Larsen-C Ice Shelf, located in the northwest portion of Antarctica’s Weddell Sea.  Brunt, whose research focus-expertise is glaciology, commented on the dynamic qualities of ice and the magnitude of the ice loss, as well as the anticipated calving of a massive iceberg from the shelf.  Brunt is currently located at …

Boisvert and Petty Featured on NASA Homepage

ESSIC assistant research scientist Linette Boisvert and post-doctoral associate Alek Petty recently published a paper that is making headlines at NASA. Their study found that during December 2015, a cyclone brought heat and humidity to a usually frigid and dry environment causing sea ice cover to thin and shrink when it grows thicker and stronger during that part of the year. Both Boisvert and Petty are quoted in the NASA article that was featured on the nasa.gov homepage. Boisvert also did …
