Atmospheric carbon monoxide (CO) distributions are controlled by anthropogenic emissions, biomass burning, transport and oxidation by reaction with the hydroxyl radical (OH). Quantifying trends in CO is therefore important for understanding changes related to all of these contributions. Here we present a comprehensive record of satellite observations from 2000 through 2011 of total column CO us...
We present and validate a method of reconstructing high-resolution sea surface wind fields from multi-sensor satellite data over the Grand Banks of Newfoundland off Atlantic Canada. Six-hourly ocean wind fields from blended products (including multi-satellite measurements) with 0.25° spatial resolution and 226 RADARSAT-2 synthetic aperture radar (SAR) wind fields with 1-km spatial resolution ha...
| H igh sea surface temperature (SST) is generally required for deep convection that reaches the tropopause. In the current climate, the SST threshold for deep convection is somewhere around 26°–27°C, depending upon region and season (Gra-ham and Barnett 1987; Waliser et al. 1993). Over such warm oceans, SST changes cause deep convective adjustment , which in turn excites the dynamic response o...
