Field sites for ground measurements of solar-induced fluorescence with examples of FluoSpec2 systems.
Half-hourly ground SIF and vegetation indices including NDVI, EVI, red edge chlorophyll index, green chlorophyll index, and photochemical reflectance index at seven crop sites in Nebraska and Illinois.
Spatial patterns of the (a) mean annual total particulate matter (TPM) from fire emissions during fire seasons from 2015 to 2020 and (b) TPM from fire emissions in October 2015 across Indonesia. Areas marked with green lines represent peatland areas. Source: Lu et al. (2022).
10-minute fire emissions within 0.1-degree regularly spaced intervals across Indonesia from July 2015 to December 2020.
Global distribution of mangrove loss and its drivers. (a) The longitudinal distribution of total mangrove loss and the relative contribution of its primary drivers. Different colors represent unique drivers of mangrove loss. (b) The latitudinal distribution of total mangrove loss and the relative contribution of its primary drivers. (c-g) Global distribution of mangrove loss and associated drivers from 2000 to 2016 at 1-degree x 1-degree resolution, with the relative contribution (percentage) of primary drivers per continent: (c) North America, (d) South America, (e) Africa, (f) Asia, (g) Australia together with Oceania.
Estimates of mangrove loss, land cover change, and its anthropogenic or climatic drivers 2000-2005, 2005-2010, and 2010-2016.
Map of measurement stations in the Boston network. The black line demarcates the 90 km radius circle in which emissions were optimized and the dashed line bounds the urban domain for study. The blue shading represents the number of housing units with natural gas per square kilometer. The red and blue contour encloses 50% of the average footprint initiated at the COP and BU sites, respectively.
Hourly average atmospheric measurements of CH4 from multiple sites in and around Boston, MA. from September 2012-May 2020
Interannual variation in gross primary productivity (GPP) across conterminous United States. Map of annual mean GPP for 2018 (a) and 2019 (b). Map of the difference in annual mean GPP between 2019 and 2018 (c) wherein red indicates higher GPP in 2019 and blue indicates higher GPP in 2018. The inset in the bottom left corner shows a time series of the average GPP across CONUS for 2018 and 2019.
Estimates of GPP for CONUS from 2018-02-15 to 2021-10-15, based on measurements of solar-induced chlorophyll fluorescence from TROPOMI on the Sentinel-5P satellite platform.
