Abstract
AbstractHistorically, atmospheric field campaigns typically focused on either meteorology or chemistry with very limited complementary observations from the other discipline. In contrast, a growing number of researchers are working across subdisciplines to include meteorological and chemical measurements when planning field campaigns to increase the value of the collected datasets for subsequent analyses. Including select trace gas measurements should be intrinsic to certain dynamics campaigns, as they can add insights into dynamical processes. This paper highlights the mutual benefits of joint dynamics–chemistry campaigns by reporting on a small sample of examples across a broad range of meteorological scales to demonstrate the value of this strategy, with focus on the Deep Convective Clouds and Chemistry (DC3) campaign as a recent example. General recommendations are presented as well as specific recommendations of chemical species appropriate for a range of meteorological temporal and spatial scales.
Highlights
Atmospheric field campaigns typically focused on either meteorology or chemistry with very limited complementary observations from the other discipline
This balance can be improved by adding relatively low-cost chemical and/or meteorological measurements to the primary proposed suite of observations. This calls for careful consideration in the initial planning of field campaigns that considers complementary chemical measurements for dynamical campaigns and complementary meteorological measurements for chemistry campaigns
The addition of atmospheric state variables to chemistry-focused field campaigns provides information on the dynamical state to quantify the uncertainty introduced by meteorological phenomena
Summary
Atmospheric field campaigns typically focused on either meteorology or chemistry with very limited complementary observations from the other discipline. Leveraging the investment already made in field campaigns to include a few additional measurements, e.g., measurements of carbon monoxide (CO) and ozone (O3) to distinguish tropospheric and stratospheric air or a wind profiler to provide insight on PBL dynamics, results in an increase in scientific value that far outweighs the extra investment. This approach was part of the planning for the Deep Convective Clouds and Chemistry (DC3; Barth et al 2015) campaign, which will be described in more detail in the third section and can be used as an example case for future campaigns.
