General Comments: The manuscript titled ‘The concentration, source apportionment and deposition flux of atmospheric particulate inorganic nitrogen during dust events’ written by Jianhua Qi presented the dust impacts on particulate inorganic nitrogen by analyzing the aerosol samples collected at Qingdao, China. The authors divided dust pattern into three parts, and investigated the dry depositio...

We employ numerical models of Mars at spatial scales ranging from global to a few metres in order to investigate both the impact of increasing dust loading on atmospheric circulations and the role of different atmospheric circulation components on dust lifting, transport and on dust storm decay. Figure 1: Typical dust lifting events, relevant spatial scales and meteorological models suitable fo...

Introduction: Dust is continuously lifted from the Martian surface and put into atmospheric suspension. This is well visible during dust devil activity [1] and planet encircling dust storms [2]. The mechanism for the atmospheric dust entrainment has been debated for a long time. Wind stress can easily put dust into suspension under Earth conditions, i.e. at ~1000 mbar surface pressure. In princ...

This study has used TOMS AI as well as the reanalysis dataset of thirty-four years (1979-2012) to investigate the influence of atmospheric circulation on dust transport during the Harmattan period in West Africa, using Aerosol Index (AI) data, obtained from various satellite sensors. Changes in Inter-Tropical Discontinuity (ITD), Sea Surface Temperature (SST) over the Gulf of Guinea, and North ...

A method is described that uses target transformation factor analysis techniques to determine the number of independently variable components and recover the spectral end-members present in a set of mixed spectra. These techniques were tested on two sets of synthetic spectral mixtures and several subsets of Thermal Emission Spectrometer (TES) data. In both synthetic mixture sets, the correct nu...

[1] Atmospheric dust disturbances ranging in size from dust devils to planet-encircling dust storms are ubiquitous on Mars. After dust devils, the most common disturbances are localor regional-scale disturbances. The origin of some of these mesoscale systems has been previously investigated and found to be linked to lifting along frontal systems or cap edge circulations. Very little attention h...
