<p>This research is a general reflection of the possible transmission not only of COVID-19 but of any influenza disease depending on environmental parameters such as solar radiation, air humidity and air temperature (vapor pressure deficit), evoking the Penman-Monteith model regarding the evaporation of the water that constitutes the small water droplets (aerosols) that carry the virus. In this case the evapotranspiration demand of the atmosphere with which it can be deduced that the spread of the disease will be higher in those places with less evaporative demand, that is, high air humidity and / or low temperatures, and / or low radiation intensities, and vice versa. It can also be deduced that the hours of greatest potential contagion are the night hours, while those with the lowest risk are between 2:00 p.m. and 4:00 p.m. On the other hand, in those rooms with low temperatures the contagion would be more effective. So, considering that the drops produced by a sneeze, by speaking or breathing can go beyond two meters away, it is roughly explained that the use of face masks and keeping a safe minimum distance of two meters can limit transmission of viruses and / or infections. However, this practice is not entirely safe as the environment can play an important role. What is recommended to reduce the spread of these pathogens is to produce high evaporative demands: increasing solar radiation, and increasing air temperature and reducing air humidity, which is practice that can be effective in closed rooms.</p>

Based on the analysis of official statistics from the Voronezh Hydrometeorological Service, the patterns of the dynamics of pollutants (formaldehyde and soot) are investigated depending on the combination of various meteorological parameters — air temperature, wind speed, relative air humidity. A positive relationship has been established between the increase in atmospheric pollution with formaldehyde and air temperature. With increasing wind speed and relative humidity, the concentration of formaldehyde and soot in the atmosphere of the city, as a rule, decrease. The maximum permissible level of carcinogenic risk to public health has been established, causing concern. The obtained patterns can be used to predict the level of technogenic pollution of the city’s atmosphere, depending on meteorological conditions.

Study Results

This paper presents the distribution features of observed meteorological parameters in Truong Sa archipelago area including wind, tropical cyclone, and average values of solar radiation, air temperature, air humidity, rainfall. Observed data were collected from Truong Sa island hydro-meteorological station. In particular, data of tropical cyclones affecting Truong Sa archipelago area were collected from the websites http://www.jma.go.jp/jma/jma-eng/jma-center/(Japan). Study results show that the main meteorological parameters in Truong Sa archipelago area are affected by solar radiation and monsoonal wind regimes in East Asia region which are Northeast monsoon occurring from November to April and Southwest monsoon occurring from June to September. Transition periods are May and October. Tropical cyclones occur mainly in November–December, maximum wind speed was 64 m/s in typhoon HAIYAN (November 2013). The highest average solar radiation occurs in April (277 hours), the lowest in January (181 hours). The highest average air temperature occurs in April (29.5oC), the lowest in January (26.6oC). The highest average rainfall occurs in November (341 mm), the lowest in March (62 mm). The highest average air humidity occurs in November–December (85%), the lowest in April–May (79%). The highest average water evaporation occurs in March (129 mm), the lowest in December (87 mm).

This study aims to analyze the role of Green Open Space on Environmental Protection in Ambon City. The method of data collection is done by collecting primary data in the form of micro climate measurements (temperature and air humidity) at each RTH location. Micro climate data is then processed using microscope office excel, to get the results of comparison tabulations and graphs. After the data tabulation value was obtained statistically analyzed by correlation test. this technique aims to determine the effect of green space on air temperature and green space on air humidity in various types of green open spaces. To analyze the effect of Green Open Space on the preservation of the environment of the city of Ambon, a Spearman correlation correlation tool with Pearson control was performed. The results showed that the results of the microclimate measurements carried out on the Green Path each way Dr. Malaiholo, Pattimura road, Piere Tandean road, Dr. Leimena, shows the air temperature and average humidity of Dr. Malaihollo 32.3 ℃ and RH 68.5%, Pattimura road 33.2 ℃ and RH 61.0%, Jalan Piere Tandean 32.5 ℃ and RH 64.0%, Jalan Dr. Leimena 33.0 ℃ and RH 56.7%. Based on the results of the Convenience Analysis, the four green lines are classified as uncomfortable because the average is in the value of> 27.

Indonesia is a tropical region with very large solarenergy where an average daily insulation of 4.5 - 4.8 KWh / m² /day. Based on this fact, solar energy is a potential form ofrenewable energy to be developed. This study aims to design aPLTS system which is the initial stage of planning PLTS systemdevelopment. This system Design uses Matlab software byutilizing the Matrix Unit Interface (GUI) Matlab to calculatethe amount of electrical load to be used, battery capacityrequirements, number of solar modules and large capacity ofthe inverter to be used. Location of the measurement datacollection takes place in the city of Pinrang, area of the Suppasub-district shrimp farm. Measurements are conducted todetermine how much solar radiation and air temperature in thepond area.
