How easily does COVID-19 spread through the air?

The COV-19 virus reportedly attaches itself to droplets which are emitted when infected people sneeze or cough or by droplets exiting an infected persons mouth when speaking. However, there are different theories of how long the virus will remain transmittable through the air. According to a new study COVID-19 appears to remain airborne longer than suspected The contaminated droplets containing ...

How Is the COVID-19 Virus Transmitted?

15 weeks into the COVID-19 pandemic, scientists know a lot more about how the disease is transmitted. The highest risk for public health is from crowded indoor spaces with poor ventilation, and especially with prolonged face-to-face interactions. In close proximity, people speaking, coughing, singing, or simply breathing can produce respiratory droplets containing the COVID-19 (SARS-CoV-2) ...

Signal to Noise Ratio Estimations for a Volcanic Ash detection lidar

In this paper we calculate the Signal-to-Noise (SNR) ratio of a 3-channel commercial volcanic ash detection system, (Raymetrics lidar model LR111-D300), already in operation for the Met Office organization. The methodology for the accurate estimation is presented for day and nighttime conditions. The results show that SNR values are higher than 10 for ranges up to 13 km for both nighttime and ...

Classification of iron oxide aerosols by a single particle soot photometer using supervised machine learning

Abstract. Single particle soot photometers (SP2) use laser-induced incandescence to detect aerosols on a single particle basis. Both refractory black carbon (rBC) and other light absorbing metallic aerosols, including iron oxides (FeOx), have been characterized by the SP2, but single particles cannot be unambiguously identified from their incandescent peak height (a function of particle mass) and ...

Year‐Round In Situ Measurements of Arctic Low‐Level Clouds: Microphysical Properties and Their Relationships with Aerosols

Abstract Two years of continuous in situ measurements of Arctic low-level clouds have been made at the Mount Zeppelin Observatory (78°56'N, 11°53'E), in Ny-Alesund, Spitsbergen. The monthly median value of the cloud particle number concentration (Nc) showed a clear seasonal variation: Its maximum appeared in May-July (65 ± 8 cm" ), and it remained low between October and March (8 ...

$Mixing characteristics of refractory black carbon aerosols determined by a tandem CPMA-SP2 system at an urban site in Beijing$

Mixing characteristics of refractory black carbon aerosols determined by a tandem CPMA-SP2 system at an urban site in Beijing

Abstract Black carbon aerosols play an important role in climate change by absorbing solar radiation and degrading visibility. In this study, the mixing state of refractory black carbon (rBC) at an urban site in Beijing was studied with a single 15 particle soot photometer (SP2), as well as a tandem observation system with a centrifugal particle mass analyzer (CPMA) and a differential mobility ...

Micro Pulse Lidar: Perfect Tool for Atmospheric Research

Micro pulse style lidars are active remote sensing tools proven to be highly useful in atmospheric research. This style of backscatter lidar has been around for decades; however, incremental improvements in photon counting, sensitivity, polarization, optical filters, coatings, and precision machining of each element support increasingly accurate analysis. Each iteration of the sensor provides a ...

Environmentally sound - Case study

On March 16, 2018, the U.S. Environmental Protection Agency (EPA) proposed to add hazardous waste aerosol cans to the category of “universal wastes” regulated under the federal Resource Conservation and Recovery Act (RCRA) regulations, codified at Title 40 of the C.F.R., Part 273. 83 Fed. Reg. 11654. According to EPA, this action would benefit the many manufacturing facilities and ...

Sources and physicochemical characteristics of black carbon aerosol from the southeastern Tibetan Plateau: internal mixing enhances light absorption

Abstract. Black carbon (BC) aerosol has important effects on the climate and hydrology of the Tibetan Plateau (TP). An intensive measurement campaign was conducted at Lulang ( ∼ 3300 m a.s.l. – above sea level), southeastern TP, from September to October 2015, to investigate the sources and physicochemical characteristics of refractory BC (rBC) aerosol. The average rBC mass ...

Aircraft and ground measurements of dust aerosols over the west African coast in summer 2015 during ICE-D and AER-D

Abstract. During the summertime, dust from the Sahara can be efficiently transported westwards within the Saharan air layer (SAL). This can lead to high aerosol loadings being observed above a relatively clean marine boundary layer (MBL) in the tropical Atlantic Ocean. These dust layers can impart significant radiative effects through strong visible and 1R light absorption and scattering, and can ...
