Abstract

GOSAT has been operated more than 5.5 years after its launch on January 23, 2009. Receiving TANSO-FTS Level 1A/1B data and TANSO-CAI Level 1A data from JAXA (FTS: Fourier Transform Spectrometer; CAI: Cloud and Aerosol Imager, JAXA: Japan Aerospace eXploration Agency), National Institute for Environmental Studies (NIES) has provided various kinds of Standard data products such as FTS SWIR Level 2 (XCO₂ and XCH₄: column concentrations of CO₂ and CH₄), FTS TIR Level 2 (vertical profiles of CO₂ and CH₄ concentration), FTS Level 4A (global CO₂ flux), FTS Level 4B (global CO₂ distribution), CAI Level 1B/1B+, and CAI Level 2 (cloud flag). After the latest updates of FTS Level 1 products to V161.160 (Version 161.160) by JAXA in 2013, now FTS SWIR Level 2 products are available as V02.21 (Version 02.21) for the entire period from April 2009 to May 2014. In March 2014, FTS Level 4 products of CO₂ (V02.02) were processed with FTS Level 2 (V02.21) for the period of June 2009 to October 2011. FTS Level 4 products of CH₄ (V01.01) were newly added to the Standard products and are available for 2 years from June 2009. FTS TIR Level 2 products (V01.0x) were updated in August 2014 and delivered to general users for 2.5 years from January 2010. There were some minor changes in their data format. After improving product search functions with an interactive map operation in GUIG (GUIG: GOSAT User Interface Gateway), general users are able to find and download these Standard products for their concerning area much easily.
