HAL Members Meeting – Thursday, June 11 at 7 PM

Hello Everyone,
Our June meeting (which is open to HAL members and the public) brings us a wonderful opportunity to explore the cutting edge of Earth‑observing science. This month’s speaker, Dr. Vanderlei Martins of UMBC’s Earth and Space Institute, will present “Advancing Earth Observation: The HARP2 Sensor on NASA’s PACE Satellite.”
HARP2 is the first U.S. hyper‑angular imaging polarimeter ever flown in space, providing global observations every two days and capturing up to 60 viewing angles in multiple wavelengths and polarization states. These measurements allow scientists to retrieve the microphysical properties of aerosols, ice and water clouds, and surface features with unprecedented detail. Dr. Martins will highlight key results from HARP2’s first two years in orbit, including observations of wildfires, dust transport, urban pollution, and aerosol‑cloud interactions – phenomena that shape our climate and environment in ways we are only beginning to fully understand.
We will also have our Book of the Month and Shallow Skies segments during the meeting. As always, I am looking forward to seeing the photos, sketches, or even artwork that our talented members have been working on. Please send your contributions to me at j...@tomney.com no later than Wednesday evening so they can be included in the Member Astrophotos portion of the meeting.
