The ORNL DAAC recently released the following new Making Earth System Data Records for Use in Research Environments (MEaSUREs) dataset by Wen, J., et al. (2021):
Global High-Resolution Estimates of SIF from Fused SCIAMACHY and GOME-2, 2002-2018
This dataset provides global solar-induced chlorophyll fluorescence (SIF) estimates at a 0.05-degree resolution (approximately 5 km at the equator) for each month from August 2002 through December 2018. SIF data (740 nm) was retrieved from the SCanning Imaging Absorption spectroMeter for Atmospheric CHartographY (SCIAMACHY) and Global Ozone Monitoring Experiment 2 (GOME-2) instruments onboard the MetOp-A satellite and was downscaled to 0.05 degree using Random Forest algorithm and harmonized with cumulative distribution function (CDF) matching technique. This dataset will inform on the synergy between satellite SIF and photosynthesis and research on drought, yield estimation, and land degradation evaluation.
The NASA MEaSUREs program is a commitment to expanding the understanding of the Earth system using consistent records. NASA has begun to deploy new types of sensors to provide three-dimensional profiles of Earth's atmosphere and surface. Emphasis is placed into linking together multiple satellites into a constellation, developing the means of utilizing a multitude of data sources to form coherent time series, and facilitating the use of extensive data in the development of comprehensive Earth system models.
Additional data from MEaSUREs and other relevant links can be found on the ORNL DAAC's MEaSUREs Project Page.
