about tile products
A
Tile products are defined in EQA (sinusoidal equal area) projection and created for each area.
These area is defined 18 segments in the latitude direction (vv) and 36 segments in the longitude direction (hh), and tile number is represented by vvhh.
The number of pixels of tile products is 4800x4800 (250m resolution) and 1200x1200 (1km resolution).
It's different the processing method between standard products and near-real-time products.
Standard product: Statistical processing each observation day. 1 file / day.
Near-real-time product: Processing each input product (scene). Multiple files / day.
Please refer following about detail information. For information on other projection methods, please refer to FAQ"Map projection (each product)", FAQ"Path and Scene Definition". Additionally, for filtering around Japan, please refer to FAQ"How to find around Japan data.".
