DATASET OVERVIEW

Abstract

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

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

http://www.chikyu.ac.jp/precip/

for the details of interpolation algorithm and input data.

DATA REMARKS

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)
