AWCI: Asian Water Cycle Initiative

The AWCI Training Course
on Improved Bias Correction and Downscaling Techniques for Climate Change Assessment including Drought Indices

Date:   18th - 20th June 2013
Venue:  University of Tokyo Hongo Campus, Tokyo, Japan

The Training Course Agenda

Objectives

  1. Capacity building. Participants will learn:
    1. Improved methods and tools necessary for processing climate model projections of future meteorological variables to be usable for assessment of climate change impacts on water resources,
    2. Application of the processed GCM output as forcing data to run WEB-DHM in their AWCI basin, and
    3. Generation of drought indices from the WEB-DHM output for historical and future periods.

  2. Preliminary Climate Change Impact Analysis in participating basins. The results obtained during the training course are expected to be usable for regional analysis of climate change impacts on water resources, in particular droughts.

Scope

  • A method for selection relevant models out of the CMIP family of general circulation models (GCMs) and necessary tools (on-line).
  • A comprehensive statistical method for bias correction of the GCM precipitation output (historical simulation and future projection) including heavy, normal and low rainfall events and using rain-gauge data provided for the AWCI CCAA study; necessary tools (on-line).
  • A statistical spatial downscaling method using available rain-gauge data within the basin; necessary on-line tools; (option to use GSMaP data to obtain spatial distribution in case of very limited number of stations will be explained but not actually used).
  • Running WEB-DHM using the bias corrected and downscaled precipitation data of one pre-selected GCM, other forcing data will also be extracted from this GCM (not bias-corrected). Only basins that participated in the March 2011 will be considered for this step, i.e. Meghna (Bangladesh), Punatsangchhu (Bhutan), Sangker (Cambodia), Citarum (Indonesia), Tone (Japan), Langat (Malaysia), Tuul (Mongolia), Shwegyin (Myanmar), Narayani (Nepal), Soan (Pakistan), Pampanga (Philippines), Kalu Ganga (Sri Lanka), Mae Wang (Thailand), Huong (Vietnam).
  • A method to generate drought indices and drought assessment method and tools using corrected precipitation outputs for past and future AND simulated river discharge by WEB-DHM. The full method using further spatial hydrological outputs by WEB-DHM (groundwater, soil moisture, surface fluxes) will be explained but not actually used for the training (time limitation).
  • In-situ data quality control tool.

Participants' Report

IMPORTANT NOTE:
Each participant of the training course will be requested to submit a brief written report (400 – 700 words) on your participation in this event, which will be included in the final reports of the APN funded projects supporting this event. This is an APN requirement and its fulfillment is expected within 1 month after the training course. A template for this your contribution with further explanation will be provided in due course.
