Faint glow from growing plants (ERS-2, daily, 1995-2003)

L2 Daily Solar-Induced Fluorescence (SIF) from ERS-2 GOME, 1995-2003
biosphere NASA ORNL_CLOUD Level 2 multiple
In plain English

What it measures. The faint glow that plants give off during photosynthesis, measured over land in large strips. Includes both raw and adjusted values plus quality and uncertainty information.

How it's made. Derived from the GOME instrument on Europe's ERS-2 satellite, covering 1995 to 2003 at a coarse resolution; the abstract notes the signal is naturally noisy and only lightly validated.

How & where you'd use it. Offers an early, historical look at plant photosynthetic activity, useful for studying vegetation health over time despite its noisiness and coarse detail.

Official description

This dataset provides Level 2 Solar-Induced Fluorescence (SIF) of Chlorophyll estimates derived from the Global Ozone Monitoring Experiment (GOME) instrument on the European Space Agency's (ESA's) European Remote-Sensing 2 (ERS-2) satellite. Each file contains daily raw and bias-adjusted solar-induced fluorescence on an orbital basis (land pixels only), at a resolution of 40 km x 320 km, along with quality control information and ancillary data. Data is provided for the period from 1995-07-01 to 2003-06-22. The GOME SIF product is inherently noisy due to low signal levels and has undergone only a limited amount of validation. This dataset includes both Version 1 and Version 2 files. Version 2 includes new fields such as SIF uncertainties, longitude-latitude corners, and data coverage over ocean. In addition, the SIF bias adjustment differs between Versions 1 and 2. The data are provided in NetCDF format.
