Atmospheric Precipitation Sampling and Analysis Methods General Rules
Atmospheric precipitation is a common component of natural hydrological, meteorological and ecological processes. Prolonged and continuous monitoring of atmospheric precipitation is necessary to understand the hydrological cycle, improve accuracy of meteorological forecasts, understand land and water resources and predict ecological systems development. The aim of this English article is to provide an overview of atmospheric precipitation sampling and analysis methods.
The primary method of atmospheric precipitation sampling is through the use of precipitation gauges. This method is highly reliable and cost effective, and is capable of storing and analyzing both relatively large and small precipitation amounts. It is important to note that the use of precipitation gauges is limited to intromission latitudes and consequently cannot be used to sample areas with tropical or polar climate.
In non-intromission areas, other methods such as radar, satellite and maser are used to measure precipitation. Radar and satellite data are used to predict and estimate rainfall in an area and in combination with precipitation gauges these data help improve the accuracy of meteorological forecasts. Radar also provides information on the path and strength of raindrops which can be useful in understanding hydrological and hydrogeological processes. Likewise, maser-based systems provide data on atmospheric humidity and can be used to measure rainfall intensity over small areas.
Another method that has recently become popular is the use of chemical tracers. In this method, a special liquid or powder is added to a known source of natural water. This tracer is then picked up by precipitation as it falls and can then be detected by special instruments or analysis techniques. This technique is often used in situations where it is difficult to determine the origin of precipitation in a particular area.
After collecting data from the field, samples can then be analysed in the laboratory using a variety of techniques. These techniques include measurement of water chemistry, isotopic analysis, particle size analysis and trace gas analysis. Each method has its advantages and disadvantages and must be used depending on the requirements of the study. The main benefits of laboratory analysis are that they can provide much more detailed information than field measurements.
Atmospheric precipitation sampling and analysis methods are important tools in the study of hydrology and the characterization ofecological systems. They allow for the determination of the origin and behaviour of precipitation in different regions, the assessment of ecological changes and the identification of water sources. This article has provided an introduction to the general principles of atmospheric precipitation sampling and analysis and discussed their importance in hydrological and ecological studies.
