Interactive comment on “Weekly patterns of aerosol in the United States” by D. M. Murphy et al

چکیده
The referee noticed that we had handled sites and clusters differently: we normalized clusters before computing the average over the continental US but did not normalize sites before calculating the weekly cycles for clusters. The referee suggested that it would be more consistent if we normalized the individual sites before averaging into the clusters. In response to this comment, we have performed the calculations both ways and the results are essentially identical. For example, the national average weekly cycle for elemental carbon changes by about 0.2% (out of about 15%) depending on whether sites are normalized or not before the clusters are averaged. This can be qualitatively seen by noting that the weekly cycles of median values (blue curves) on the

How Can a Global Social Support System Hope to Achieve Fairer Competiveness?; Comment on “A Global Social Support System: What the International Community Could Learn From the United States’ National Basketball Association”
Ooms et al sets out some good general principles for a global social support system to improve fairer global competitiveness as a result of redistribution. This commentary sets out to summarize some of the conditions that would need to be satisfied for it to level up gradients in inequality through such a social support system, using the National Basketball Association (NBA) example as a point ...

We offer a UK-based commentary on the recent “Perspective” published in IJHPM by Thakkar and Sullivan. We are sympathetic to the authors’ call for increased funding for health service and policy research (HSPR). However, we point out that increasing that investment – in any of the three countries they compare: Canada, the United States and the United Kingdom– will ipso facto not necessarily lea...

The study by Henze et al. ”Global modeling of secondary organic aerosol formation from aromatic hydrocarbons: Highvs low-yield pathways” investigates the global relevance of recent simulation chamber results that parameterize the NOx dependence of SOA yields from benzene, toluene and m-xylene, by Ng et al. (2007). The paper is generally well written, and presents the results on the NOx dependen...
