    AIRS provides satellite retrieval of mid-tropospheric carbon dioxide even under cloudy conditions, without the use of a priori information from models. AIRS retrievals use cloud-cleared thermal IR radiance spectra in the 15 micron band with an accuracy better than 2 ppm. AIRS retrievals have been used to produce global maps of carbon dioxide and other trace gases…

    Accumulated sediments at the bottom of lakes are invaluable archives of past climate and environmental change. These sediments contain a variety of physical, geochemical, and biological proxy indicators that can be used to gain a multi-faceted understanding of past conditions. Unlike other high-resolution paleoclimate archives, such as tree rings, corals, and speleothems…

    Annual net land-atmosphere carbon flux and net flux of carbon to the atmosphere due to land-use and land-use change (LULUC) are estimated using an integrated assessment model and three historical reconstructions of land use and land use conversion. The data span 1800-2010 and are aggregated for nine regions of the globe.

    • to

    GOSIF is a global, gridded dataset of solar-induced chlorophyll fluorescence (SIF). SIF, an energy flux re-emitted by plants a few nanoseconds after light absorption, exhibits a strong linear relationship with gross primary production (GPP) at the ecosystem scale and thereby is a strong proxy of GPP. The GOSIF dataset (Li and Xiao, 2019a) provides 8-day SIF data globally…

    The Global Land Evaporation Amsterdam Model (GLEAM) is a satellite remote sensing-based set of algorithms dedicated to the estimation of evaporation and soil moisture at global scales (Miralles et al. 2011). The current version of GLEAM (version 3) operates at a daily time step with a spatial resolution of 0.25 degrees (Martens et al. 2017). The dataset consists of two…

    Directly measured and continuous records of atmospheric carbon dioxide (CO2) extend back to 1958. CO2 has also been measured in ancient air samples trapped in ice cores, and these records extend back hundreds of thousands of years. More recently, CO2 is being sampled by satellites providing global data to researchers.
