![]() Monitoring Instrument (TROPOMI) aboard the Copernicus Sentinel-5P mission in Before that, the advent of the TROPOspheric ESA's FLuorescence EXplorer mission, scheduled for launch afterĢ025, will enable a breakthrough in the spatial resolution of space-based SIFĭatasets ( Drusch et al., 2017). Precision errors and the low spatial resolution and/or sparse spatial The main limitations of those SIF datasets for scientific work are the high Gross primary production (GPP) of different ecosystems The SIF data from those missions haveīeen typically used to investigate the spatial and temporal patterns of the Originally intended for atmospheric research, such as GOME-2 Number of global SIF datasets have been produced from spaceborne spectrometers Were first achieved in late 2011 from the GOSAT mission Terrestrial vegetation has been shown to be a closer indicator of vegetationįunctioning than other variables traditionally derived from optical remote The sun-induced fluorescence (SIF) signal emitted by the chlorophyll a of The TROPOSIFĭataset is available through the following digital object identifier (DOI): ![]() Initial data quality assessment are presented in this work. ![]() Methodology to derive SIF and ancillary data as well as results from an Important ancillary variable to be used in combination with SIF. Within the 665–785 nm range are also included in the TROPOSIF dataset as an Reflectance spectra at seven 3 nm windows devoid of atmospheric absorption Ratio at the expense of a higher sensitivity to atmospheric effects. This provides an enhanced signal-to-noise A secondary SIF dataset derived from an extended fitting window Baseline SIF retrievals are derived from the 743–758 nm Version of the TROPOSIF dataset covers the time period between May 2018 andĪpril 2021. Within the TROPOSIF project funded by the European Space Agency. Work, we present a global SIF dataset produced from TROPOMI measurements Spatial and temporal sampling than earlier satellite instruments. Situation, as TROPOMI provides daily global measurements at a much denser Mission and the high quality of its data products promise to alleviate this The recent advent of the Copernicus Sentinel-5P TROPOMI Signal-to-noise ratio of the data hamper their application over small orįragmented ecosystems. Of vegetated areas worldwide, but the coarse spatiotemporal sampling and low Theseĭatasets have been useful to monitor the dynamics and productivity of a range Global SIF datasets with different spectral, spatial, and temporal sampling characteristics have become available to the scientific community. The first satellite-based global retrievals of terrestrial sun-inducedĬhlorophyll fluorescence (SIF) were achieved in 2011.
