DATA PROCESSING

Data Processing (1)

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

VnGP is a daily gridded data set made from the data of 481 rain gauges in Vietnam. The “Spheremap”of Willmott et al. (1985) interpolation method was used. The Spheremap method is originally the weighted two-dimensional spatial interpolation algorithm proposed by Shepard (1968), but modified to work with the spherical coordinates. We have not taken into account of topographical effects, nor the systematic errors of the rain gauges' data.

USE CONSTRAINTS

Data Policy by Data Provider

This data set requires permission by the data provider (contact person) before you can download. The content of this dataset should not be used for commercial purposes.

The terms of data use of data providers take first priority over the DIAS data usage policy. In the event a data provider has not established terms of use, the following DIAS project data terms of use apply.

1. Users shall prioritize and abide by terms of use stipulated by a data provider in the event such exist

2. The use of DIAS data sets is limited to research and educational purposes [*1]

3. Users shall not modify the content of DIAS data sets

4. Users shall not provide the content of DIAS data sets to third parties

5. In the event of using DIAS data sets in an academic presentation, paper, article, or report, etc., users shall cite in parenthesis the text given as the data citation

6. In the event of using DIAS data sets in an academic presentation, paper, article, or report, etc., users shall submit a copy of the work (an offprint in the case of a paper, or a copy of the lecture summary in the case of an oral or poster presentation) to the DIAS office below

[*1] Data sets whose commercial usage are allowed under the data policy by data provider will be also allowed to be used commercially as DIAS data sets, after ongoing preparation works have been completed. Please contact the DIAS Office for more details.
