GCOM-C/SGLI L3 Leaf Area Index (V2)

  • This dataset, JAXA/GCOM-C/L3/LAND/LAI/V2, provides the sum of one-sided green leaf area per unit ground area.

  • The data is available from January 1, 2018, to November 28, 2021, with a daily cadence.

  • GCOM-C conducts continuous global observations using the SGLI sensor to study radiation budget and carbon cycle mechanisms.

  • The dataset includes bands for Leaf Area Index (LAI_AVE) and LAI QA flags, along with various image properties.

  • This dataset is free to use with proper attribution to the Japan Aerospace Exploration Agency (JAXA).

Description

This product is the sum of the one-sided green leaf area per unit ground area.

For data after 2021-11-28, see the V3 dataset.

GCOM-C conducts long-term and continuous global observation and data collection to elucidate the mechanism behind fluctuations in radiation budget and carbon cycle needed to make accurate projections regarding future temperature rise. At the same time, cooperating with research institutions having a climate numerical model, it contributes to reduction of errors in temperature rise prediction derived from the climate numerical model and improvement of accuracy of prediction of various environmental changes. SGLI mounted on GCOM-C is the succession sensor of the Global Imager (GLI) mounted on ADEOS-II (MIDORI II) and is the Imaging Radiometer which measures the radiation from near-ultraviolet to thermal infrared region (380 nm-12 um) in 19 channels. Global observation of once for approximately every two days is possible at mid-latitude near Japan by observation width at ground greater than 1,000 km. In addition, SGLI realizes high resolution than the similar global sensor and has a polarized observation function and a multi-angle observation function.
