Asian Precipitation - Highly-Resolved Observational Data Integration Towards Evaluation (APHRODITE's ) of Water Resources project develops state-of-the-art daily precipitation and temperature datasets with high-resolution grids for Asia. The datasets are created primarily with data obtained from a rain-gauge-observation network.

Product APHRO_JP offers gridded daily precipitation of Japan for 1900-2011.

Data Processing (1)

General Explanation of the data producer's knowledge about the lineage of a dataset

The gridded fields of daily precipitation are defined by interpolating

gauge observations obtained from meteorological stations throughout the region.

Please refer to


for the details of interpolation algorithm and input data.


For long-term change analyses, we provide dataset calculated from constant observation through the analysis period. (DPREC.CSTN)

Details on quality control method of our product is described in Kamiguchi et al.(2010, 2011)
