Water and Energy Balance
Study (WEBS) is an activity under GEWEX Hydrometeorological Panel (GHP)
to integrate activities of Continental Scale Experiments (CSEs) of
which GAME is a member. Since autumn of 2002, we joined the GAME
International Science Panel to promote WEBS.
The purpose of WEBS can be summarized as follows from our viewpoint.
- We want to know the global energy and water cycle
quantitatively. For that goal, we must use some global data sets. Most
of them are not direct observations, but either compiled from satellite
observations or produced by data assimilation with numerical weather
prediction models. In order to have good global budgets, we should
evaluate the global data sets with more direct observations. The
comparison can be useful both to selection of global data sets to be
used immediately, and to improvement of global data sets in the next
generation.
- A CSE can reveal climatic and hydrological characteristics
of that
region much better than before. Then, it will be fruitful to compare
CSEs in different climatic zones along the same axis of water and
energy balance components, in order to build up knowledge about
diversity and commonness of water and energy cycle over the globe.
- We recommend the synthesis of all available measured and
numerically-derived values to understand water and energy balance over
the monsoon region. This may be one way to utilize data collected
during the GAME Phase II for seeking scientific outcomes. For example,
we can calculate the continental-scale cloud-radiation interactions by
combining the satellite observations such as ISCCP with GAME reanalysis
products from which the evolution of radiation energy budget can be
examined in conjunction with the monsoon progress.
