TL;DR: In this article, the authors report on the development of an inexpensive radiative condenser for collecting atmospheric vapor based on the experience gained using a small working model in Grenoble (France), a prototype of 10×3 m2 was established in Ajaccio (Corsica, France).

TL;DR: In this article, the ice nucleating ability of four kinds of pollen in the immersion and contact freezing modes was investigated at the Mainz vertical wind tunnel with freely suspended supercooled droplets at temperatures down to −28 °C.

TL;DR: In this article, an approach which can be seen as an adaptation of deterministic meteorological model outputs is described, which involves searching for a sample of past situations similar to the current one from a long meteorological archive.

TL;DR: In this article, a project in northern Chile was undertaken to determine the origin and behaviour of fog in the coastal and inland locations of the Tarapaca Region, and the results are important for understanding of fog formation and dissipation along the coastal mountain range and for the recognition of potential sites for the installation of fog water collectors, which can be used as a water source in the Atacama Desert.

TL;DR: In this article, a 10-year fog climatology of Germany and adjacent areas, based on NOAA-Advanced Very High-Resolution Radiometer (AVHRR) data, is presented.

TL;DR: In comparing the results of the tracking algorithm with those from four test persons, TRACE3D shows a promising performance, and hence, it seems possible to apply this algorithm as a nowcasting tool.

TL;DR: In this article, data on groundwater salinisation and fog deposition were collected at villages of the indigenous communities and at the Gobabeb Training and Research Center (GTRC) in the Central Namib Desert.

TL;DR: In this article, an analysis of the data using back trajectories showed a dependence of the aerosol extinction on the origin of the air mass, and only a small part of the total variability could be explained by the local air mass origin.

TL;DR: In this paper, the chemical compositions of intercepted clouds have been investigated at more than a dozen locations across the United States, including pristine and heavily polluted locations, and the pH values range from below 3 to above 7.

TL;DR: In this article, a one-dimensional forecast model for radiation fogs and low-level stratiform clouds is presented to improve the local visibility forecast on airports and other traffic locations where fog and low level stratus frequently occur.

TL;DR: In this article, an analysis was made of a historical set of meteorological data collected at the University of Bologna agrometeorological station (Cadriano), between 1952 and 1999.

TL;DR: In this paper, the authors used estimates of PM, PM10 and PM2.5 made from the mass size distributions measured regularly using a Quartz Crystal Microbalance (QCM) impactor for the period October 1998-December 2000 at the coastal station Trivandrum.

TL;DR: In this article, a micro-meteorological station was installed in the field next to a modified Hiltner balance, and a microlysimeter with an undisturbed soil sample was placed nearby.

TL;DR: Two fog water collection systems (FWCS) have been implemented in South Africa as discussed by the authors, one at a high elevation site at the Tshanowa junior primary (JP) school in the Soutpansberg located in the Northern Province and the other near a small rural community at Lepelfontein along the West Coast.

TL;DR: In this paper, the authors compared the data obtained at Falda Verde with those obtained at five other Chilean fog stations over a total time period running from 1987 to 2001.

TL;DR: In this paper, a field campaign was carried out in the NW Negev desert, Israel, in September and October 1997, to collect meteorological data and carry out dewfall measurements.

TL;DR: In this paper, the chemical characteristics of rainfall and its seasonal variation at the EMEP (The Cooperative Programme for Monitoring and Evaluation of the Long-range Transmission of Air Pollutants in Europe) station located in Cubuk, Ankara were studied for the period between September 1994 and December 1996.

TL;DR: In this article, the influence of interparticle electrical forces on the particle collection rates of charged water drops is investigated using a particle-droplet trajectory model, and a threefold increase in the collection efficiency is found for aerosols carrying up to 10 elementary charges, collecting submicron aerosol.

TL;DR: In this paper, the authors investigated fog meteorology, fog chemistry and fog deposition on epiphytic bryophytes from July 2000 to June 2001 in the Yuanyang Lake forest ecosystem.

TL;DR: In this article, the eddy covariance method was used to measure the fogwater deposition fluxes of inorganic compounds dissolved in fog and rain for two different ecosystems in Europe.

TL;DR: In this article, a new procedure for characterising the water soluble organic compounds (WSOC) in fog water, for which information is still rather limited, was set up, which allows a quantitative determination of three main classes of organic compounds.

TL;DR: In this article, a stainless steel active fogwater collectors were designed and used in Davis (CA, USA) to collect fogwater for the speciation of organic matter, including various alkanes, polycyclic aromatic hydrocarbons (PAH) and alkanoic acids.

TL;DR: In this article, the relationship between radar-derived hail kinetic energy and hail damage to residential and agricultural buildings is presented for nine hail cells that occurred over the Swiss Mittelland (1992-1999).

TL;DR: In this paper, the authors compared the performance of 16 different measurement systems (i.e., adiabatic expansion condensation, flow diffusion condensation particle counter, turbulent mixing condensation (TCCP), laser optical particle counter and electrostatic particle measurement system) in the measurement of total aerosol particle number.

TL;DR: In this article, the authors evaluated the possibility of obtaining water for different uses of the local population (domestic, agricultural, cattle raising and forestry), by means of fog collectors (FCs).

TL;DR: In this article, a Gaussian distribution of saturation excess within a model grid box is used to model the distribution of liquid water content within a grid box and assess how well each predicts the mean autoconversion rate.
