Data oco-2 sif

OCO-2 will enable measurements within a narrow swath with sufficient accuracy for 5km x 5km spatial scales—an unprecedented resolution for SIF measurements from space. The measurement technique itself is also robust against occurrences of atmospheric aerosols and thin clouds, which typically affect purely optical-based remote sensing techniques.

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. We have reached a point where an ensemble of existing (GOME-2, GOSAT, OCO-2, TanSat, TROPOMI) and future (OCO-3, GeoCarb) Earth observations provide SIF data products to research and application communities. We proposed a half-day technical workshop for SIF data products, current research, applications and advantages and limitations of SIF. Abstract and Figures We assess CO2 emissions from the Nile Delta region of Egypt, using over five years of column-averaged CO2 dry air mole fraction (XCO2) data from the NASA's OCO-2 satellite.

OCO-2 will enable measurements within a narrow swath with sufficient accuracy for 5km x 5km spatial scales—an unprecedented resolution for SIF measurements from space.

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 NASA’s OCO-2 mission is collecting a dense, global set of high-spectral resolution measurements that are used to estimate and SIF. The OCO-2 mission data set can now be used to assess This product, SIFoco2_005, was derived from Orbiting Carbon Observatory-2 (OCO-2) SIF observations was produced by training an artificial neural network (ANN) on the native OCO-2 SIF observations and MODIS BRDF-corrected seven-band surface reflectance along OCO-2's orbits.

Data and Retrieval 2.1. TROPOMI - Instrument Overview TROPOMI [Veefkind et al., 2012] is the single payload of the Sentinel 5 Precursor (S-5P) satellite, which was successfully launched on 13 Sep 29, 2020 OCO-2 SIF data included in the target region and having the target land cover type were identified and averaged for each month. OCO-2 SIFs derived from the nadir mode and the glint mode were averaged separately. The mean LAI and the mean local time of the observation were calculated in the same way as SIF. In this study, we utilized recent SIF data with high spatial resolution from two satellite instruments, OCO-2 and TROPOMI, together with multiple other datasets.

Apart from OCO-2, there are no official SIF retrievals from the other satellites but an abundance of independent retrievals, which can vary substantially from one another. The lack of a consistent SIF data record, including inter-calibration of different satellites currently hampers scientific interpretation, especially with respect to analysis
