7. DATASET OVERVIEW

7.1 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 APRHO_PR offers gridded daily precipitation of Eurasia (combined region) for 1951-2007.

8. DATA PROCESSING

8.1 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.
