Cloud Product

Development of Cloud Product (Plan) Step 1: Algorithm Decision - JMA/MSC has reviewed the algorithms of cloud products for MSG by NWC SAF and for GOES-R by NOAA/NESDIS - JMA/MSC plans to create the new algorithm based on that of NWC SAF - Some part of NOAA/NESDIS algorithm will be introduced Step 2: Coding Software - Cloud mask, cloud type/phase: almost completed - Cloud height: completed Step 3: Threshold Values - Preparation of Look Up Tables - Adjustment of threshold values Step 4: Validation CGMS-41 2013/7/8 -12 JMA-WP-06

Volcanic Ash Product

Development of Volcanic Ash Retrieval Software for Himawari-8/9 (Plan) Step 1: Introducing EUMETSAT Volcanic Ash Retrieval software for MSG in JMA/MSC by March 2013 - JMA/MSC has installed software on the computer system and applied it to MTSAT-2 in collaboration with EUMETSAT - The new volcanic ash product started to be provided for VAAC/Tokyo in pre-operation mode (March, 2013) Step 2: Introducing NOAA/NESDIS Volcanic Ash Retrieval software in JMA/MSC in collaboration with NOAA/NESDIS - JMA/MSC and NOAA/NESDIS had a technical meeting on the Volcanic Ash Retrieval algorithm and software - Procedure to install NOAA/NESDIS software is ongoing Step 3: JMA/MSC will operate above two products in parallel and provide to VAAC/Tokyo after Himawari-8 will be in operation Step 4: Further verification and improvements will be done in cooperation with EUMETSAT and NOAA/NESDIS CGMS-41 2013/7/8 -12 JMA-WP-06

Progression Status of Volcanic Ash Product since Nov. 2012 • LUT from EUMETSAT (November, 2012) • First VA retrieval experiment for Mt. Shinmoe, Mt. Bulusan and Mt. Tolbachik (December, 2012) • Technical meeting with EUMETSAT and UKMO (28 th January – 1 st February, 2013) • Technical meeting with NOAA/NESDIS (25 th February – 1 st March, 2013) • Volcanic ash product started to provide for VAAC/Tokyo in pre-operation mode (March, 2013) • WMO 6 th Volcanic Ash Science Workshop (11 -15 March, 2013, Indonesia) CGMS-41 2013/7/8 -12 JMA-WP-06

Dust Product

Development of Dust Product (Plan) • Product will be developed for the purpose of monitoring of Asian dust • Two different approaches, one from visible and near-infrared data and another one from infrared data, will be taken for the product • Algorithm for visible data product has been developed based on NOAA/NESDIS Aerosol algorithm • NOAA/NESDIS volcanic ash algorithm will be applied for the product from infrared data CGMS-41 2013/7/8 -12 JMA-WP-06

Progress on Development of Visible Data Based Dust Product • Reviewed ATBD for NOAA/NESDIS aerosol product (2012. 4 -6) • Designed LUT for aerosol retrieval and generated 1 st version of LUT (2012. 8 -11) • Experimental retrieval from MODIS L 1 B data (2012. 12) • Mie scattering and radiative transfer calculation tools for LUT calculation developed by JMA/MRI are being installed to JMA/MSC computer system • Algorithm and/or LUT will be adjusted using Himawari-8 data after the data becomes available CGMS-41 2013/7/8 -12 JMA-WP-06

Example (Optical Depth, 01 May 2011) New Algorithm with MODIS/Terra (0430 UTC), without cloud mask CGMS-41 2013/7/8 -12 Current Algorithm with MTSAT-2 (0500 UTC) JMA-WP-06

Plan for infrared based Dust Product • MSC is planning to use NOAA/NESDIS volcanic ash algorithm for aerosol Product • Development will be started after MSC received the NOAA/NESDIS software for volcanic ash • The β-ratio of Asian dust for the software will be calculated in advance by the end of this year CGMS-41 2013/7/8 -12 JMA-WP-06
