The range of latitudes in the southern hemisphere is limited during this season because the sun is near it northernmost latitude. 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. 21.10.2020

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.

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.

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. during the time period over which vegetation is revealed through snowmelt. Conversely, SIF …

OCO-3 uses the same instrument as OCO-2, but it has been adapted to work on the ISS. the OCO-3 instrument has an agile 2-D pointing mechanism, i.e., a Pointing Mirror Assembly (PMA) that allows for rapid transitions in pointing. The PMA is used to collect Snapshot Area Maps (SAMs) which are data collections over ~80km by 80km in 2 minutes. REZZO1–2 byly použity nejčerstvější údaje, tj. údaje z roku 2010.

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. It is the second successful high-precision (better than 0.3%) CO 2 observing satellite, after GOSAT

Over the last few months, OCO-2 has been finishing the reprocessing of the entire OCO-2 data record (2014 to present). This new version, version 10 or V10, reflects updates to the data processing software to "improve the quality of the now five and three-quarter year record of atmospheric Carbon Dioxide (XCO2) and Solar Induced Chlorophyll Fluorescence (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. A NASA mission, it is a replacement for the Orbiting Carbon Observatory which was lost in a launch failure in 2009. Target observations over Lauder, New Zealand show negligible airmass dependence. Target Observations over the TCCON station at Armstrong/Dryden show more air mass dependence.

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. Our SIF estimates are
For OCO-2, the SIF prior is taken from the official SIF retrieval, as described in Sun et al. , because SIF retrievals from individual soundings are meaningful for OCO-2 due to its relatively high SNR.

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. In general, compared with the other two datasets, the GOSIF dataset exhibits the best performance in estimating GPP, regardless of the extraction range.
