8Special Features of CAWSES Space Weather Theme,
2004-2008
- Goal Collaborative analysis of international
sun-to-Earth data sets aimed at answering open
questions in space weather understanding
prediction - Main Strategy Sun-to-Earth campaigns
(pre-planned, real-time based on delta sunspot or
retrospective) driven by science questions - New Feature
- Progressive development of new global data
analysis tools that require international
collaboration - worldwide maps of geophysical quantities (ex
ULF wave power, hmF2, nmF2, high-resolution GPS
TEC, etc.) - continuous time-series of solar observations
(ex continuous H alpha solar images) - Use of new global data analysis tools in
combination with other satellite ground-based
data in campaigns to address science questions in
ways that were not possible before. - Capacity Building Data sharing as a powerful
capacity building exercise in developing nations.
Puts local observations into the global view.
9CAWSES Global Research Tools
- Created by a working group, consisting of
representatives from observing sites, who decide
on - the best parameters to display
- the needed algorithms to integrate the data from
different sites (possibly on the fly) - the most useful graphical displays
- Efficient data access
- The recruitment of observing sites in critical
locations - Where possible, use recruitment of sites as a
capacity building tool - Suggest space weather campaigns or retrospective
analysis efforts that utilize the global science
analysis tools ( other data) to address cutting
edge science questions
10Value of CAWSES to IHY, eGY, IPY
- Progressively develop a set of new international
data analysis tools - Valuable asset for space research
- Combined with satellite data they give new ways
of investigating important science questions - Lasting legacy after IGY celebrations
- Collect preserve comprehensive sets of
international sun-to-Earth observations - Valuable for developing assimilative space
weather models - Important for testing understanding and
predictive capabilities of sun-to-Earth models - Worldwide resource for sun-Earth system science
during and after IGY - Build up an international community familiar with
campaign tools collaborative analysis ready to
participate in the IGY - Help refine science questions and needs for
worldwide campaigns over the next 2 years in
preparation for the IGY celebration.
11- Critical Joint Needs with IHY, eGY, IPY Data
Environment - Baseline Need Seamless access sun-to-earth data
sets worldwide (including developing nations) --
through Virtual Observatories? - Wish List
- High level, analyzed and intepretted data by
instrument teams - On-the-fly generation of integrated data products
(world-maps, continuous time series) constructed
by networks of worldwide observatories - Summary data on a common time or spatial axis at
vantage points throughout the geospace system - Mapping between regions
- Tracking of science questions that develop
- Smart data searches (looking for similar
features, similar events, statistics in Virtual
Observatories) - Model simulations as data sets
- viewed along satellite trajectories
- mapped to ground-based sites
- Plotted with observations in common format
- post-processed quantities (i.e., Poynting flux, B
field energy, etc.) - Support for assimilative models
- Secure proprietary data sharing for space weather
user community

- To the FFT, Dst looks like a very low frequency
(lt 1 mHz) wave cycle. - Spectral leakage into higher frequency
components. Unusually large Dst means unusually
large leakage. - Sharp drop in Dst interpretted as high frequency
components in PSD
