  1. HIMAWARI-8/9 CLOUD, VOLCANIC ASH AND DUST PRODUCTS In Response to Action 40.24CGMS-41 / JMA-WP-06

  2. Cloud Product

  3. 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 JMA-WP-06

  4. Examples 1512UTC 7th Apr. 2012 RGB Image R: A0.64 G: A0.86 B: T11.2 Cloud Mask JMA-WP-06

  5. Examples 1512UTC 7th Apr. 2012 fractional very high opaque high opaque medium opaque low opaque very low opaque semi-trans p. thick sem. meanly thick semi-trans p. thin Cloud Top Altitude (m) Cloud Type JMA-WP-06

  6. Volcanic Ash Product

  7. 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 Development of Volcanic Ash Retrieval Software for Himawari-8/9 (Plan) JMA-WP-06

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

  9. Examples Mt. Merapi 2010.11.11 2000UTC Mt. Sarychev 2009.6.14 0300UTC Mt. Bulusan 2011.2.21 0400UTC Mt. Shinmoe 2011.1.27 0000UTC JMA-WP-06

  10. Dust Product

  11. 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 JMA-WP-06

  12. 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 1st version of LUT (2012.8-11) • Experimental retrieval from MODIS L1B 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 JMA-WP-06

  13. Example (Optical Depth, 01 May 2011) New Algorithm with MODIS/Terra (0430 UTC), without cloud mask Current Algorithm with MTSAT-2 (0500 UTC) JMA-WP-06

  14. 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 ofAsian dust for the software will be calculated in advance by the end of this year JMA-WP-06
