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.

OCO-2 Description: We used the global, OCO-2-based SIF product (GOSIF) and linear relationships between SIF (Solar-induced chlorophyll fluorescence) and GPP to map GPP globally at a 0.05° spatial resolution and 8-day time step for the period from 2000 to 2017. To account for

The retrieval window of OCO-2 SIF at 757 nm is 758.1 to 759.2 nm, which is not identical to that used by GOSAT, because the edge of the short-wavelength side of the O 2 A band is different between GOSAT and OCO-2. Therefore, it is expected that the GOSAT SIF is higher than the OCO-2 SIF because of the spectral shape of SIF.
global, OCO-2-based SIF data set (GOSIF) with high spatial and temporal resolutions (i.e., 0.05°, 8-day) using discrete OCO-2 SIF soundings, remote sensing data from the Moderate Resolution Imaging Spectroradiometer (MODIS), and meteorological reanalysis data.

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.

GOSIF - The GOSIF product is a new global, OCO-2-based SIF (solar-induced chlorophyll fluorescenc) data set with high spatial and temporal resolutions (i.e., 0.05-degree, 8-day) over the period 2000-2018 based on discrete OCO-2 SIF soundings, remote sensing data from MODIS, and meteorological reanalysis data (Li and Xiao, 2019a). Crisp: OCO-2 Mission 16 Preliminary Results from OCO-2 Target Observations • Preliminary OCO-2 target overflights are yielding new insights into biases and random errors. Target observations over Lauder, New Zealand show negligible airmass dependence. With OCO-2, scientists can observe these tiny changes for the first time, a first step toward understanding the sensitivity of the carbon cycle to climate variations on a scale of years to decades. A New Way to Measure Photosynthesis. Besides carbon dioxide, OCO-2's high-resolution spectrometers can observe solar-induced fluorescence, or SIF.
Additionally, we used solar-induced fluorescence (SIF) measurement from OCO-2 to understand how the CO2 emissions are related to agricultural activities. 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.

Spatially averaged 2014 seasonal cycle of MODIS EVI, OCO-2 SIF/cos(solar zenith angle, SZA), and GOME-2 SIF/cos(SZA) across Alaskan tundra. during the time period over which vegetation is revealed through snowmelt. 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.

OCO-2 SIF and MODIS VIs (EVI, NDVI) were compared for estimating the autumn crop production and the factors a ff ecting the accuracy of estimation were also analyzed. 2. Moreover, the results show that the observation mode of OCO-2 has an evident impact on the accuracy of estimating GPP using OCO-2 SIF products.

Additionally, few attempts have been made to verify if SIF products from the new Orbiting Carbon Observatory-2 (OCO-2) satellite could be applied for regional corn and soybean yield estimates. 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. 500 80 a 7 600 430 32 800 50 oco 8 000 0,0002 ha o, 76 4 300 328000000 9 cm; výška hranolu = 5 km-2 20 oco cm2 760 000 n-,m2 43 dm2 328 dm2 Ve étyFbokém hranolu vypocítej chybející velitiny. = 368 cm*, délky hran obdélníkové podstavy a = i4 cm, b — — 8 cm 12 240 mm2; délka hrany obdélnll 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. 9/9/2019

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).
