AMS Annual Meeting 2022 logo

ESSIC/CISESS at AMS Conferences

The American Meteorological Society (AMS) Annual Meeting was held virtually this year from January 23 to 27. Simultaneously, AMS held a number of specialized conferences and symposiums, focusing on topics including hydrology, climate variability and change, and atmospheric chemistry. ESSIC/CISESS scientists contributed a large number of talks and posters at the event. Talks included:

Innovative Use of Satellite Data Establishes Water Clarity Improvement at Restored Oyster Reefs

Ron Vogel, ESSIC senior faculty specialist, recently co-authored a NOAA Technical Memorandum with colleagues from NOAA’s National Marine Fisheries Service, titled “Using Satellite-Derived Total Suspended Matter Data to Evaluate the Impacts of Tributary-Scale Oyster Restoration on Water Clarity.” In the study, the team sought to explore whether large-scale oyster restoration in the Chesapeake Bay, on the order of 100s of acres, can produce improvements in water clarity that are measurable, and whether satellites can be a tool to help measure that change.

Jiang Leads International Effort to Create New Data Standard for Oceanographic Research

ESSIC/CISESS Scientist Li-Qing Jiang, who works on the Ocean Carbon Acidification Data System (OCADS) project at the National Center for Environmental Information (NCEI), coordinated a massive effort by the international community to develop a best practice data standard for discrete bottle-based chemical oceanographic data. The study, co-authored by ESSIC/CISESS Scientist Alex Kozyr and esteemed scientists at over 30 institutions in 10 countries, was published on January 21st in Frontiers in Marine Science.

CISESS Presents Two AMS Short Courses

Scott Rudlosky and Joseph Patton led an AMS short course titled “Accessing and Applying Geostationary Lightning Mapper Observations” on January 5 and 6. This two-part course introduced the GLM observations and imagery using GLM flash skeletons and gridded products used by the National Weather Service. Participants were shown how to access archived and real-time imagery before conducting a hands-on exercise illustrating their new-found skills. Additional information can be found at this link: Accessing and Applying Geostationary Lightning Mapper Observations.

Marine Heat Waves in the Arctic Ocean

ESSIC/CISESS/SCSB visiting research scientist Tom Smith has a new article in press at Geophysical Research Letters that analyzes events of extremely warm waters in the oceans known as marine heatwaves (MHWs).

NOAA Daily Optimum Interpolation Sea Surface Temperature (DOISST) Version 2.1

ESSIC/CISESS Visiting Research Scientist Tom Smith is coauthor of an article on DOISST v.2.1 coming out in the September 2021 issue of the Journal of Climate. The paper, titled “Assessment and Intercomparison of NOAA Daily Optimum Interpolation Sea Surface Temperature (DOISST) Version 2.1”, shows how the improved NOAA operational analysis compares to several other available analyses.
