- Specific goal for this project is to develop a
biospheric nowcast and forecast system useful for
monitoring and predicting key ecosystem variables
relevant in natural resources management

Cooler springs after 1998
Change in Spring (March-April-May) Temperature,
oC 1998-2004 - 1991-1998
Late budbreak Slow ripening Delayed
harvest Increasing risk from frost

25Summary
Summary
Unprecedented data volumes Working with large
data sets requires robust automation Planning/Exe
cution technologies allow integration of
distributed heterogenous
data sets TOPS is not model-centric, allowing
rapid adaptation to new domains Potential for
mimicking the weather service with ecological
forecasts of various lead times Characterizing
and communicating the uncertainty in ecological
forecasts remains a challenge
