Outline
A short training course on precipitation measurement from space and its applications
will be programmed for participants from Asia-Pacific regions as a part of Japanese contribution
to the International Hydrological Program (IHP). The course is composed of a series of lecturesand practice sessions.
Objectives
Precipitation is one of the major components of the Earth climate system. Precipitation
has also a big impact as a major fresh water resource to the ecosystem and human activity. Thus,
observation of precipitation distribution is crucial not only for understanding and predictingchanges of precipitation under the current global climate change but also for human activities.
Global or even locally, precipitation observation is, however, difficult, because it has large
spatiotemporal variations.
Progress of Earth observation technology from space is remarkable. The observation
targets are land/ocean surface conditions, air quality, cloud distribution, etc. Precipitation is oneof the major targets of Earth observation from space. However, the spatial and temporal
resolutions and accuracy of the rain retrieval from space are far from sufficient. To meet therequirements, along with the sensor and rain retrieval algorithm developments, other ideas toconstruct global precipitation maps have emerged. One is the so-called "constellation" satellites
in which multiple satellites data are utilized to construct global precipitation maps. The other isdata merging in which the satellite precipitation data and ground-based rain gauge data are
combined. Nowadays, several satellite-satellite based precipitation maps have already been
available, and tests on utilization of the maps to short-term weather forecast, river runoff
prediction and flood warming have already started.
In this training course, the basics of precipitation retrieval from space and current
global precipitation maps will be introduced. The accuracy will also be included. Examples ofglobal precipitation maps from space will be demonstrated. Practices are for learning skills toutilize the precipitation maps.

Downloading the Textbook for Participants from the Net
The textbook of “the 22nd IHP Training Course”, which is converted in PDF style, will
be prepared and will be put on the IHP Nagoya forum website of “www.ihpnagoyaforum.org”.
The participants are requested to download such a PDF file from the website in advance as apreparation to the several lectures of the training course. The textbook should be constituted ofcontents (referred sentence bodies, figures, tables, pictures, equations and observed/calculatedresults) with authorized copyrights.
Web broadcasting the Lectures
The lectures except with the exception of field trips will be webcasted to someuniversities in Asia via the UNESCO Office Jakarta and with other technology facilities. The
slide materials will be distributed to the participants from the Net in advance. The materials arerequested to be filtered out whenever copyrights apply in case of web broadcasting; part or its
whole slides will be masked out with digital treatments such as overlaying mosaic images orwith black-out screening during web broadcasting.
