These recent results are intriguing, but it should be noted that the trends are observed over relatively short, recent periods and have
limited spatial domains.
These subcontinental spatial units can be chosen to coincide not only with regions of high observational density but also
with spatial domains defined by large - scale climate features.
For his entire career, Noguchi focused on
the spatial domain that sculpture could evoke.
Key issues identified in inland and marine presentations included the need to standardize
the spatial domain, minimize double counting of emissions from lakes and wetlands, reduce bias in field site selections, improve measurements of cold season emissions, and improve scaling of hot spots.
This is likely because we maximized the covariance between the sea ice field and the atmospheric circulation by restricting our time averaging to the seasonal mean and restricting
our spatial domain to 0 ° — 180 ° W and 30 ° — 75 ° S. Inevitably, indices calculated from local data will explain more local variance than those based on remote data.
