The manuscript deals with a topic appropriate for ACP presenting the analyses of aerosol optical properties gathered during an experimental campaign in the GangeticHimalayan region. Although the study period roughly covers a complete annual seasonal cycle, the variety of variables potentially available for the study makes it really worthy. Bellow there are general and particular comments to hel...

#2. It is unclear why the authors only consider dust: the same problem should exist for other sources of iron as well, or probably even worse, especially finer particles from combustion? Why not consider those? You could presumably do this rather easily, just assuming BC has Fe, and including the size distribution of BC? There are recent reviews of the size of combustion iron particles (e.g. Wa...

This paper concerns two-hop communication over relay-assisted Block fading channel. It is assumed there is not a direct link between the transmitter and the affiliated destination and the communication occurs in two hops through the use of a relay, where the amplify and forward (AF) strategy is employed at this node. In this case, in a Rayleigh block fading channel, the optimal weight function ...

Many modern communication signal formats, such as orthogonal frequency-division multiplexing (OFDM) and code-division multiple access (CDMA), have high peak-to-average power ratios (PARs). A signal with a high PAR not only is vulnerable in the presence of nonlinear components such as power amplifiers (PAs), but also leads to low transmission power efficiency. Selected mapping (SLM) and clipping...
