We developed a global ‘OCO-2’ SIF data set (GOSIF) with high spatial and temporal resolutions (i.e., 0.05°, 8-day) over the period 2000-2018 based on discrete OCO-2 SIF soundings, remote sensing data from the Moderate Resolution Imaging Spectroradiometer (MODIS), (MODIS), and meteorological reanalysis data …

With the deep neural networks (DNN) approach, this study investigated the ability of OCO-2 SIF, MODIS EVI, and climate data to estimate county-level corn and soybean yields in the U.S. Corn Belt. - Negative correlation with OCO-2 SIF.

The Orbiting Carbon Observatory‐2 (OCO‐2) collects solar‐induced chlorophyll fluorescence (SIF) at high spatial resolution along orbits (oco2_orbit), but its discontinuous spatial coverage precludes its full potential for understanding the mechanistic SIF‐photosynthesis relationship. 13/10/2017 Orbiting Carbon Observatory-2 (OCO-2) is an American environmental science satellite which launched on 2 July 2014.
In the OCO-2/3 B10 SIF Lite data product, the actual SIF retrievals are performed at 757 and 771 nm, and SIF at 740 nm is derived from these two values based on the following relationship: SIF@740nm = 1.5 ∙ ( SIF@757nm + 2∙SIF@771nm ) / 2 Product File Structure Users of previous OCO-2 SIF Lite files (prior to Build 10) will find that the file 15/12/2020 ral resolution. Though space borne SIF retrievals are considered to be the better representative of photosynthetic activities compared to NDVI, LAI, fAPAR, etc., the scattered measurement by OCO-2 restricts its usage from local to global scale. This work focuses on the global mapping of the SIF retrievals of OCO-2 by combing two traditional corre- In this work, we used OCO-2 SIF data (OCO2_L2_Lite_SIF.8r). W e selected all flux towers in North America, which have both SIF757 and SIF771 data (SIF at retrieval bands 757 and 771 nm) and GPP Our results show that OCO-2 SIF, along with GOSAT products, closely resemble the mean spatial and temporal patterns of FLUXCOM GPP from regions to the globe.
- Most of positive anomalies are found near the large cities and industrial area. Systematic changes of XCO 2 over whole Korea domain occurred in August 2015. OCO-2 observes The Orbiting Carbon Observatory-2 (OCO-2), launched in July 2014, is capable of measuring Solar-Induced chlorophyll Fluorescence (SIF), a functional proxy for terrestrial gross primary productivity (GPP). High Resolution Global Contiguous SIF Estimates Derived from OCO-2 SIF and MODIS This dataset provides high-resolution, spatially-contiguous, global solar-induced chlorophyll fluorescence (SIF) estimates at 0.05 degree (approx. 5 km at the equator) spatial and 16-day temporal resolution beginning in September 2014 and continuing to the present. OCO‐2 SIF showed strong correlations with tower GPP at both midday and daily timescales, with the strongest relationship observed for daily SIF at the 757 nm (R 2 = 0.72, p < 0.0001). Strong linear relationships between SIF and GPP were consistently found for all biomes ( R 2 = 0.57–0.79, p < 0.0001) except evergreen broadleaf forests ( R 2 = 0.16, p < 0.05) at the daily timescale.

OCO‐2 SIF provides retrievals at 757 and 771 nm. To reduce random noise, this paper used the average of both wavelengths scaled to 757 nm using a weighting factor: (SIF 757 + 1.5 × SIF 771)/2, instead of using SIF 757 only as in Zhang et al. (2018).

Finally, we estimated an average emission of CO2 from the Nile Delta from 2014–2019 of 470 Mt CO2/year, about 1% of global anthropogenic emissions, which is significantly more than estimated hitherto.
