Forcing in the Stratosphere

March 28th, 2007 · No Comments

Recently I read an interesting paper in science magazine titled Anthropegenic and Natural Influences in the Evolution of Lower Stratospheric Cooling by V. Ramaswamy et al. Different atmospheric forcings (natural and anthropogenic) and their degree of influence are analyzed using data and models. NOAA satellites, specifically channel 4 of the microwave sounding unit (MSU), provide [...]

IPCC SPM Overview

February 14th, 2007 · No Comments

Here is a copy of the presentation I gave at last week’s ATOC journal club on the IPCC SPM report.  It’s basically a regurgitation of the information in the SPM and in my previous post on what’s new in the AR4 SPM compared to TAR.  It’s not exactly the most exciting presentation, but I invite [...]

Comments on “An important constraint on tropical cloud – climate feedback” by Hartmann and Larson

February 9th, 2007 · No Comments

I think this paper is very interesting, but I have to admit that I don’t understand it very well. Hopefully, this post will spur some useful discussion. Here’s the citation info: Hartmann, D. L. and K. Larson, “An important constraint on tropical cloud – climate feedback,” Geophys. Res. Lett. 29, doi:10.1029/2002GL015835, 2002. The authors’ primary [...]

IPCC SPM – So What’s new?

February 2nd, 2007 · 4 Comments

Much of the information that is in the IPCC Summary for Policymakers is not news to those of us who are in the atmospheric science community and follow the literature. Even though we try, things do tend to slip through the cracks, and it takes someone (or 2500+ people, to be precise) to distill the [...]
