Asian Precipitation - Highly-Resolved Observational Data Integration Towards Evaluation of Water Resources
(APHRODITE's Water Resources)
The APHRODITE project develops state-of-the-art daily precipitation datasets with high-resolution grids for Asia. The datasets are created primarily with data obtained from a rain-gauge-observation network. The status of data collection and the domains we use to create the daily grids are shown on the Products page.
APHRODITE's Water Resources project has been conducted by the Research Institute for Humanity and Nature (RIHN) and the Meteorological Research Institute of Japan Meteorological Agency (MRI/JMA) since 2006. Our domestic members are listed here.
Our approach and objectives are presented on the Scope page. We welcome various types of collaboration, particularly the collection of rain-gauge-observation data and feedback from grid-data users. Our collaborators are listed here.

Since we released the product V0804 in May 2008, we have made continuous efforts to collect data and improve quality control and the analysis method. We have begun releasing V0902 after in-house checking. The previous test version (V0902_pre) has been replaced with 0.5-degree and 0.25-degree gridded daily precipitation data for the period of 1961–2004 over Monsoon Asia (MA_V0902), the Middle East (ME_V0902) and Russia (RU_0902). The differences from the previous versions are detailed in "readme", and remaining problems "errata" are reported on this website. We welcome any feedback including your problems and requests for future improvements.

The APHRODITE project has been given a two-year extension that will run until March 2011 because of good reviews of our first three years of activity. We thank everyone for their cooperation.
