Valerie Pasquarella led Spring School workshop for Argentinian Space Agency
CRS Research Assistant Professor Valerie Pasquarella was invited to lead a 3-hour hands-on workshop on time series analysis and land cover change mapping as part of a week-long program on remote sensing and space systems organized by the Argentinian Space Agency in September 2022. The hybrid session covered topics including exploratory analysis, temporal segmentation algorithms, anomaly detection […]
Demystifying LandTrendr and CCDC temporal segmentation
Valerie Pasquarella led a publication with co-authors Paulo Arévalo (BU/CRS), Kelsee Bratley (BU graduate student), Eric L Bullock (USFS, formerly BU/CRS), Noel Gorelick (Google), Zhiqiang Yang (USFS), and Robert Kennedy (OSU) reviewing the LandTrendr and Continuous Change Detection and Classification (CCDC) temporal segmentation algorithms. The review, which was published in the International Journal of Applied Earth Observation and Geoinformation, […]
Dynamic World: Near real-time global 10 m land use land cover mapping
Valerie Pasquarella co-authored a publication in Nature Scientific Data with colleagues from Google, National Geographic Society, and the World Resources Institute (WRI) introducing Dynamic World, a new near-real-time global land cover dataset. The dataset, which includes class probabilities and Top-1 label predictions for all Sentinel-2 L1C imagery with less than 35% cloud cover, was released earlier this year as an Earth […]
Examining the competing effects of contemporary land management vs. land cover changes on global air quality
2021 Wong AYH and Geddes JA. Examining the competing effects of contemporary land management vs. land cover changes on global air quality, Atmospheric Chemistry and Physics, doi: 10.5194/acp-21-16479-2021 In this publication, we used satellite-derived land cover products from 1995-2015, in combination with global chemical transport modeling, to examine how land cover and land management […]
Changes in the relative importance of biogenic isoprene and soil NOx emissions on ozone concentrations in nonattainment areas of the United States
2022 Geddes JA, Pusede SE, Wong AYH, Changes in the relative importance of biogenic isoprene and soil NOx emissions on ozone concentrations in nonattainment areas of the United States, Journal of Geophysical Research Atmospheres, doi: 10.1029/2021JD036361 In this publication, we used satellite-observations of nitrogen dioxide to infer trends in anthropogenic emissions of nitrogen oxide […]
Measurement-Model Fusion for Global Total Atmospheric Deposition Initiative (2021-2023)
Jeff Geddes is the principal investigator on this grant funded by Environment and Climate Change Canada. This project is aimed at combining ground measurements, satellite observations, and chemical transport modeling to predict global atmospheric deposition of nitrogen- and sulfur-containing compounds. The deposition of these compounds impact ecosystem productivity and biodiversity, but global maps of deposition […]
CO2-Air Quality Urban Synthesis and Analysis Project: Trends & Drivers of Urban Emissions from Past, Present, to Future (2020-2023)
Jeff Geddes and Lucy Hutyra are co-investigators on a NOAA project that will examine urban trends in carbon dioxide and air pollutant emissions. The project is led jointly with the principal investigator John Lin (University of Utah) and co-investigator Steve Wofsy (Harvard). This project includes analysis of ground-based remote sensing measurements of NO2, CO, CH4, […]
