P.1155 left column 5th paragraph: "Atmospheric deposition sampling and organic components: To obtain the atmospheric samples, [investigators] used two standard passive MTX ARS 1010 automatic deposition collectors. These collectors can discriminate between dry and wet atmospheric deposition using a humidity sensor that activates an aluminum lid that covers or uncovers the dry or wet collector depending on the meteorological conditions. Each collector has an exposed area of 667 cm^2 and is 30 cm in height. The collectors are placed on a metallic structure with 1.1 m legs." |

P.1158 left column bottom paragraph: "[Investigators] quantified the wet and dry deposition of (free and attached) viruses and bacteria above the atmospheric boundary layer at the Observatory (OSN) and Veleta Peak (VSN) in Spain, and demonstrated that in each square meter, tens of millions of bacteria and billions of viruses are deposited each day. Total (free and particle-attached) deposition rates of viruses by atmospheric washout (wet collectors) ranged from 0.31 × 10^9 to 3.84 × 10^9 viruses per m^2 per day and by sedimentation (dry collectors) from 0.26 × 10^9 to 3.89 viruses per m^2 per day in 2008 (Fig. 2a Table S1), whereas, rates for bacteria ranged from 0.88 to 5.78 × 10^7 cells per m^2 per day by washout, and from 0.55 × 10^7 to 2.80 × 10^7 cells per m^2 per day by sedimentation (Fig. 2b Table S1)." |
