SUMMARY:NOAA Seminar Series: Merged LEO-GEO Tropospheric Nitrogen Dioxide (tropNO2) Product for Air Quality Applications
DESCRIPTION:Title:  Merged LEO-GEO Tropospheric Nitrogen Dioxide (tropNO2) Product for Air Quality Applications\n \nPresenter(s): Thomas Ely \nDate: 21 October 2024 12:05 pm – 12:35 pm ET\n \nRemote Access: Google Meet joining info \nVideo call link:  https://meet.google.com/yyu-ektc-gms \nOr dial: (US) +1 402-803-1147 PIN: 602 419 188# More phone numbers:  \nhttps://tel.meet/yyu-ektc-gms?pin=2445253511123 \nAbout Speaker: Thomas Ely \nAbstract: Air quality is a key societal issue and can be hard to predict in coastal cities such as New York City and Baltimore due to the effects of sea breeze. Air quality studies can benefit from more accurate retrievals of nitrogen dioxide (NO2) from geostationary satellite sensors that show the transport and spatial distribution of pollution throughout the day. The objective of this project is to implement and test a methodology that can improve the quality of geostationary (GEO) satellite NO2 data using low Earth orbit (LEO) satellite NO2 data. This methodology uses the Kalman Filter algorithm to merge the two datasets in a process similar to data assimilation\, except that the background model field uses data from a GEO satellite sensor\, which in this case is NASA’s Tropospheric Emissions: Monitoring of Pollution (TEMPO) satellite sensor. LEO data from Sentinel5-Precursor TROPOspheric Monitoring Instrument (Sentinel-5P TROPOMI) serves as observational information. The Kalman Filter adds TROPOMI measurements to the background\, weighting each dataset based on their respective uncertainties\, which can mitigate uncertainties in each of the original datasets\, resulting in a more accurate tropospheric NO2 product that retains the high temporal resolution of TEMPO data. The merged TEMPO-TROPOMI product is compared against the Pandonia Global Network (PGN) ground-based tropospheric NO2 column retrievals to evaluate the performance of the merged product compared to the original products. This project demonstrated the feasibility of implementing the Kalman Filter for merging satellite datasets and generated a new tropospheric NO2 product that can be useful for local air-quality monitoring.The results are from the NOAA EPP/MSI CSC NERTO graduate internship project that was conducted with NOAA mentor Dr. Shobha Kondragunta of NOAA NESDIS. The NERTO aligns with NOAA CSC CESSRST-II’s goal to have students conduct NOAA mission-aligned research. The NERTO Merged LEO-GEO Tropospheric Nitrogen Dioxide Product also deepened the intern’s understanding of NOAA satellite product development and validation\, as well as satellite sensor calibration.

SUMMARY:NOAA Seminar Series: Implications of Tropospheric Mass Flux Reduction for the frequency and intensity of convective precipitation
DESCRIPTION:Title: Implications of Tropospheric Mass Flux Reduction for the frequency and intensity of convective precipitation\n \nPresenter(s): Carlos Ordaz \nDate: 21 October 2024 12:45 pm – 1:15 pm ET\n \nRemote Access: Google Meet joining info \nVideo call link: https://meet.google.com/hje-hbpt-pcx  \nOr dial: (US) +1 575-942-2063 PIN: 424 547 711#  \nMore phone numbers: https://tel.meet/hje-hbpt-pcx?pin=1703364648658 \nAbout Speaker: Carlos Ordaz \nAbstract: Tropical precipitation will change with warming. Some results suggest that tropical precipitation extremes will increase at rates higher than Clausius-Clapeyron scaling of 7% per Kelvin. As a first step in building physical understanding of tropical precipitation changes\, we apply the framework established by Pendergrass and Hartmann in their 2014 (PH14) trilogy to idealized cloud-resolving models in radiative convective equilibrium. PH14 introduce a way to understand changes to precipitation distributions in two modes: the shift and the increase mode. We explain the values of the shift and increase modes in terms of physical principles. The shift mode is captured to first order by Clausius Clapeyron scaling\, while the increase mode is a combination of Clausius-Clapeyron scaling and the decrease of mass flux expected with climate change. This work contributes to a better process-level understanding of the physical mechanisms that influence tropical precipitation in a changing climate\, which can in turn be used to improve NOAA’s models.The results are from the NOAA EPP/MSI CSC NERTO graduate internship project that was conducted with NOAA mentor\, Nadir Jeevanjee of the Geophysical Fluid Dynamics Laboratory (GFDL)\, Princeton. The NERTO aligns with NOAA CSCCESSRST-II goal of furthering our understanding of the atmosphere. The NERTO Implications of Tropospheric Mass Flux Reduction for the frequency and intensity of convective precipitation also deepened the intern’s understanding of atmospheric physics.

SUMMARY:NOAA Seminar Series: Characterizing Hub-height Wind Speed Dependence on Atmospheric Processes in an Offshore Wind Environment
DESCRIPTION:Title:Characterizing Hub-height Wind Speed Dependence on Atmospheric Processes in an Offshore Wind Environment\n \nPresenter(s): Akarshna Iyer \nDate: 21 October 2024 1:30 pm – 2:00 pm ET\n \nRemote Access: Google Meet joining info \nVideo call link:  https://meet.google.com/ayt-tqzz-bsn \nOr dial: (US) +1 901-399-8908 PIN: 203 110 642#  \nMore phone numbers: https://tel.meet/ayt-tqzz-bsn?pin=5479909107077 \nAbout Speaker:Akarshna Iyer \nAbstract: Wind energy is a form of renewable energy that has been growing in implementation and use over the past years. However\, this situation is rapidly changing\, with several new offshore leases being issued to advance offshore wind energy generation. NOAA and other organizations\, including the DOE\, have sponsored the third Wind Forecast Improvement Project (WFIP3)\, a coordinated field campaign and analysis designed to improve offshore wind forecasting. This work focuses on the characterization of low-level jets (LLJs)\, jet streams found in the lower troposphere\, that take place over Block Island\, RI\, and Nantucket\, MA (two of the WFIP3 sites). The research questions this work seeks to answer are: Is the meteorology of the LLJ region consistent for multiple LLJ events? What is the meteorology pattern when an LLJ is present (offshore)\, and why? Individual LLJ cases were analyzed using observations from various WFIP3 remote sensing instruments. Preliminary results suggest\, through analysis of the thermodynamic structure of the marine atmospheric boundary layer\, that LLJs with predominantly southerly flow seem to correlate with warm air advection and periods of strengthened near-surface stability. The mechanisms that drive LLJs in regions off the U.S. East Coast are relatively unknown\, making it an important area of study\, especially since LLJ events seem to have larger errors in the High-Resolution Rapid Refresh (HRRR) model’s wind forecasts. The presence of LLJs and their shear levels can affect overall wind power generation and cause unwanted damage to wind turbines. This research benefits the science community and society because improved wind energy forecasts will increase energy reliability. The results are from the NOAA EPP/MSI CSC NERTO graduate internship project that was conducted with NOAA mentor Dr. David Turner of NOAA Research\, Global Systems Laboratory (GSL)\, Boulder\, CO. The NERTO aligns with NOAA CSC CESSRST-II’s goal to conduct NOAA mission-aligned collaborative research; the mission is To understand and predict changes in climate\, weather\, ocean\, and coasts. The NERTO deepened the intern’s understanding of NOAA\, and her results will inform future analyses of the HRRR using WFIP3 data\, resulting in a faster understanding of errors within the HRRR as a function of weather conditions during low-level jet events.

SUMMARY:NOAA Seminar Series: Phytoplankton monitoring and mapping using NOAA OAR/AOML satellite data products for urban waters ecosystems.
DESCRIPTION:Title: Phytoplankton monitoring and mapping using NOAA OAR/AOML satellite data products for urban waters ecosystems.\n \nPresenter(s): Carolina Perez \nDate: 21 October 2024 2:05 pm – 2:35 pm ET\n \nRemote Access: Google Meet joining info \nVideo call link:  https://meet.google.com/yjc-yvec-nkm \nOr dial: (US) +1 929-269-1887 PIN: 429 915 143#  \nMore phone numbers: https://tel.meet/yjc-yvec-nkm?pin=1379180679958 \nAbout Speaker: Carolina Perez \nAbstract:  Harmful Algal Blooms (HABs) significantly threaten coastal communities and public health\, impacting marine ecosystems and local economies. These blooms indicate potentially toxic phytoplankton and reflect broader environmental issues such as eutrophication\, runoff\, and the effects of weather events on coastal areas. My research focuses on the monitoring of HABs in New York City waterbodies\, specifically Randall’s Island and the Gowanus Canal\, in collaboration with NOAA’s National Centers for Coastal Ocean Science (NCCOS)and the National Phytoplankton Monitoring Network (PMN). The Gowanus Canal\, a notable study area\, was designated a Superfund site by the EPA in 2010 due to its severe contamination from runoff and combined sewage overflow.During my time at AOML\, as part of my NERTO research project\, I helped develop a research technique by combining satellite data and ground-based data to develop interactive web tools to enhance the real-time monitoring of marine ecosystems. While a NOAA AOML NERTO Intern\, I contributed to enhancing sustainability and resilience for marine ecosystems and coastal communities. AOML’s Ocean Chemistry and Ecosystem Dynamics (OCED) branch employs satellite observations to analyze sea surface temperature (SST) and chlorophyll-a (CHL) levels in water bodies. Using the Environmental Research Division’s Data Access Program (ERDDAP)\, data on SST and CHL I was able to generate detailed maps of these parameters using MATLAB. Integrating satellite-based data with in-situ measurements offers a powerful approach to understanding the health of both open ocean and coastal ecosystems. Combining these data sources\, the research aims to create synthesis products that examine algal blooms and their dynamics.The results are from the NOAA EPP/MSI CSC NERTO graduate internship project that was conducted with NOAA mentors Dr. Chris Kelble and Dr. Enrique Montes of the NOAA Atlantic Oceanographic and Meteorological Laboratory\, Ocean Chemistry and Ecosystem Dynamics (OCED) branch. This NERTO aligns with NOAA CSC’s goal of Resilient Coastal Communities and Economies through the theme of Oceans and Coasts. The NERTO deepened the intern’s understanding of NOAA’s research practices by giving me firsthand experience with the teamwork and dedication of a NOAA research team.
