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

6. Volcanic Ash Product

7. 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

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

12. Progress on Development of Visible Data Based Dust Product
Reviewed ATBD for NOAA/NESDIS aerosol product ( )
Designed LUT for aerosol retrieval and generated 1st version of LUT ( )
Experimental retrieval from MODIS L1B data ( )
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

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

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 of Asian dust for the software will be calculated in advance by the end of this year
