Newly available space-based measurements of carbon monoxide (CO) from the MOPITT (Measurements of Pollution in the Troposphere) instrument offer a unique perspective on tropospheric chemistry. We present a synthesis inversion of CO emissions from various geographical regions and for various source categories for the year 2000 using MOPITT CO retrievals. We find a large discrepancy between our t...

Observed correlations between atmospheric concentrations of CO and CO represent potentially powerful information for improving CO surface flux estimates through coupled CO -CO inverse analyses. We explore the value of these correlations in improving estimates of regional CO fluxes in East Asia by using aircraft observations of CO and CO from the TRACE-P campaign over the NW Pacific in March, 20...

For Co and CoNi single layer films, the coercivity is a linear function of the inverse layer thickness and has an angular dependence of a fourfold-like symmetry although only a uniaxial anisotropy exists. For both as-prepared and post field-cooled Co/FeMn bilayers, the exchange field and the coercivity enhancement are proportional to the inverse Co thickness. For as-prepared ones, the exchange ...

[1] We use aircraft observations of continental outflow over the western Pacific from the Transport and Chemical Evolution over the Pacific (TRACE-P) mission (March– April 2001), in combination with an optimal estimation inverse model, to improve emission estimates of carbon monoxide (CO) from Asia. A priori emissions and their errors are from a customized bottom-up Asian emission inventory for...

This paper considers the word problem for free inverse monoids of finite rank from a language theory perspective. It is shown that no free inverse monoid has context-free word problem; that the word problem of the free inverse monoid of rank 1 is both 2-context-free (an intersection of two context-free languages) and ET0L; that the co-word problem of the free inverse monoid of rank 1 is context...

[1] We use an inverse model analysis to compare the top-down constraints on Asian sources of carbon monoxide (CO) in spring 2001 from (1) daily MOPITT satellite observations of CO columns over Asia and the neighboring oceans and (2) aircraft observations of CO concentrations in Asian outflow from the TRACE-P aircraft mission over the northwest Pacific. The inversion uses the maximum a posterior...
