APHRODITE: Asian Precipitation - Highly-Resolved Observational Data Integration Towards Evaluation of Water Resources

APHRODITE’s (Asian Precipitation - Highly-Resolved Observational Data Integration Towards Evaluation) daily gridded precipitation is the only long-term (1951 onward) continental-scale daily product that contains a dense network of daily rain-gauge data for Asia including the Himalayas, South and Southeast Asia and mountainous areas in the Middle East. The number of valid stations was between 5000 and 12,000, representing 2.3 to 4.5 times the data available through the Global Telecommunication System network, which were used for most daily grid precipitation products. The products are available on a regional basis.

NOTE: The web site: http://www.agrometeorology.org/topics/agromet-market-place/announcement-aphrodite-precipitation-data contains: "The APHRODITE project has successfully ended in March 2011"

Unfortunately, many data links are no longer valid.

Key Strengths:

  • High density and quality station network.

Key Limitations:

  • Station network changes with time and season.
  • We do not homogenize the observed time series of temperature data. Changes in gauges, location of the stations, and many other factors might cause discontinuity of observation data.
  • Lack of observation data (in India, Indonesia and Papua New Guinea)

we need this data to research on spring persistent rains in southeast China

I tried in vain to download Aphrodite data. For the link "http://www.chikyu.ac.jp/precip/cgi-bin/aphrodite/script/aphrodite_cgi.cg..." the result is "404 NOT FOUND". So please check the link to the download page. Can you help me?
