Abstract:
I will present opinions, developed during a varied research-scientist career, on what helps a proposal succeed and what advice might be useful to early-career investigators. My advice is based primarily on my experience as a program office at the NSF but also from other roles in my career, including as a university faculty member, an NCAR scientist, and for almost 10 years a postdoc advisor as director of the Advanced Study Program. The talk will have three main parts: how to develop the project idea, how to develop a detailed project design, and how to avoid common problems when writing the proposal. My comments focus also on suggested ways to use grants to further your career, how to learn about grant opportunities, and how to communicate with program officers. I hope that this talk might be useful to those who expect to seek grants to fund parts of their research.

Abstract:
Data visualization is an appealing and fun craft. If done well, it can support realism in scientific reasoning, for example by layering the texture of weather and useful indicators of uncertainty (such as an ensemble of different data products) onto the smooth abstractions of climate statistics. These days, large time-aggregated archives of many reanalysis and satellite-observational datasets are available via OpenDAP. UCAR/Unidata’s free Integrated Data Viewer (IDV) and related softwares are in good shape to take advantage of these, obviating the need for downloading and organizing dataset collections. There is just the small matter of software complexity to contend with. I will show a few pretty (and scientific) results, and describe my efforts to salvage lasting value from much obsessive toil behind the scenes by assembling a newbie-friendly self-updating IDV Plugin, pointing to an ever-improving Web-hosted collection of templates and other user resources. I am trying to make it easier to gain the IDV’s great strength - rich, multi-source data integrations - for myself and my students, and for others.

Abstract:
The tactical approach to funding; eagerly scanning the announcements for something that might work, then repackaging an old proposal to see if it will fit is clearly not working. Success rates have plummeted in the past couple of decades, falling as low as 10% in some disciplines. In this chat and discussion - which will include no overheads - we will consider how to take a more strategic view, developing relationships and establishing new directions. While this takes time to get going, in the long run we shall see it is by far the best approach.

Abstract

Roughly 30 tons of interplanetary dust enters the Earth’s atmosphere every day, although estimates of this number vary from 2 to 300 tons, depending on where the estimate is made between the Earth’s surface and space. Most of the dust particles completely ablate at heights between 80 and 120 km. The resulting metal vapours (Fe, Mg, Si and Na etc.) then oxidize and re-condense to form nm-size particles, termed “meteoric smoke”. These particles are too small to sediment downwards. Instead, they are transported by the general circulation of the atmosphere, taking roughly 5 years to reach the surface. There is great interest in the role they play as condensation nuclei - of noctilucent ice clouds in the mesosphere, and polar stratospheric clouds in the lower stratosphere - and in the ability of these particles to remove acidic gases.

In this talk I will describe laboratory kinetic experiments made with a novel mass spectrometer, complemented by electronic structure calculations and statistical rate theory, to understand how metal atoms are converted into smoke particles. The process is in some ways analogous to the formation of silicate dust in stellar outflows, the main difference being the much lower temperatures (~200 K). I will then describe the first global atmospheric model of meteoric metals and meteoric smoke, which we have developed by combining three components: the Whole Atmosphere Climate Community Model (WACCM) from the US National Center for Atmospheric Research, including the CARMA particle microphysics module; a description of the neutral and ion-molecule chemistry of five metals (Na, Fe, K, Mg and Si) based on the rate coefficients of more than 120 reactions measured by the Leeds group; and a meteor input function which combines the Leeds Chemical Ablation Model with an astronomical model of cosmic dust in the inner solar system.

The model has been evaluated against a number of available ground-based lidar measurements covering a wide range of latitudes in both hemispheres, as well as with global observations of the Na and K layers using the OSIRIS spectrograph on-board the Odin satellite. The predicted meteoric smoke distribution in the atmosphere is compared with optical extinction measurements made using the SOPHIE spectrometer on the AIM satellite, and number density measurements made during the HotPay 2 rocket experiment at Andøya, Norway. In general, the model performs well in simulating both the atomic metal layers and the meteoric smoke distribution above 60 km. The implications of smoke particles in the stratosphere and ocean bio-geochemistry will be discussed.

By the Clean Air Act, the U.S. Environmental Protection Agency (US EPA) is required to monitor, regulate and set national ambient air quality standards (NAAQS) for ozone along with other pollutants considered to be harmful to public health and the environment. To investigate ozone exposure, the EPA utilizes monitoring devices sparsely located across the United States along with estimates of gridded ground-level ozone concentration produced by a deterministic numerical air quality model, Models-3/Community Mesoscale Air Quality Model, CMAQ CMAQ. To investigate about the exceedance behavior of ozone relative to the NAAQS which is given in terms of the level of the annual fourth highest ozone concentration, we propose a downscaling modeling approach that employs a spatial fourth highest extreme value (FHEV) model to assimilate both data sources. In particular, the FHEV incorporates spatially-varying parameters that depend on a smoothed CMAQ output. We apply our approach to the annual fourth highest ozone concentration in the Eastern United States during years 2001-2008 and obtain an improved predictive performance compared to that of other downscaler models.

There is a perception that no climate model has simulated the recent plateau of global warming that started around 2000.  This warming slow-down is commonly referred to as the “early-2000s hiatus”.  Though the multi-model ensemble average of uninitialized climate models indeed shows early-21st century warming greater than what has been observed, there are a number of individual ensemble members from several models that did actually simulate the early-2000s hiatus.  Those simulations were successful because the internally generated naturally occurring climate variability associated with the negative phase of the Interdecadal Pacific Oscillation (IPO) happened, by chance, to coincide with the observed negative phase of the IPO that contributed to the early-2000s hiatus.  However, picking out those skillful ensemble members in advance would not have been possible in the 1990s prior to the hiatus, and thus would have had no predictive value.  If the recently developed methodology of initialized decadal climate prediction could have been applied in the 1990s, both the negative phase of the IPO in the early 2000s as well as the hiatus could have been predicted.  The processes associated with this skillful prediction include more heat being mixed into the subsurface ocean as indicated by positive (downward)  net surface heat flux over the global ocean, and stronger Pacific trade winds that intensify the Pacific Ocean subtropical cells and mix more heat into the subsurface ocean.

The Weather Research and Forecasting (WRF) model tutorial will be offered during a two week period from 21 July - 1 August 2014 at the NCAR Foothills Laboratory, Boulder, Colorado.  The tutorial will be divided into 4 sessions:  Basic WRF (21-25 July), WRFDA (28-30 July), WRF Regional Climate (30 July), and WRF Chem (31 July - 1 August). Basic knowledge of atmospheric science and numerical modeling, as well as working in a Unix computer environment, is required. All participants are strongly encouraged to work through one or more of the online tutorials for WRF-ARW, and WRFDA, depending on interest, in advance. Register early, as registration always exceeds capacity.
