Palas ® Meet the needs of maritime surveying and expand more technological possibilities

In May of this year, the Department of Environmental Science and Engineering at Fudan University conducted academic research on atmospheric science. This project is dedicated to studying atmospheric aerosols and their impact on air quality and regional climate. This experiment was conducted at sea for more than 20 days of navigation observations, combining field observations, numerical simulations, remote sensing product applications, and other research methods. To ensure the accuracy of the measurement data, the research team from Fudan University chose Palas ® As the primary measuring instrument. Palas ® The measurement results meet the high standard requirements for data in this experiment, and with its performance advantages, it overcomes the more complex and varied climate and navigation environment compared to land, providing strong technical support for the experiment.

Stable measurement in harsh maritime environments

Before going out to sea, researchers conducted long-term observations near Huludao in Liaoning Province, which belongs to the northern temperate continental monsoon climate with an annual average temperature of no more than 9 ℃*Low temperature can reach-23.3℃。The data collection point for this navigation experiment was selected in the Bohai Sea area, which is the northernmost coastal area with a total coastline of about 3800 kilometers. In order to obtain more accurate experimental data, it is necessary to install the instrument on the ship and obtain monitoring data results while sailing.

Not afraid of wind and waves

The situation at sea is more complex compared to land, with higher humidity and salt content. Therefore, data collection in such high salt and high humidity environments can cause certain corrosiveness to measuring instruments and equipment. During this navigation experiment, it lasted for a long time20During the multi day process, the weather conditions also bring more challenges to researchers. During the experiment, there are often strong winds, thunder and heavy rainstorm. Not only that, researchers also need to face the shaking caused by wind and waves on the ship, which indirectly affects the performance of the instruments and even leads to instrument damage. To ensure the smooth progress of the experiment, a set of monitoring instruments that can overcome these problems is needed. in the process ofPalas®After a thorough understanding, Fudan University's research institutions chosePalas® AQ Guard AmbientThe air quality monitor was used as the monitoring instrument for this experiment.

Portable and preciseAQ Guard Ambient

The reason why the research team chosePalas® AQ Guard AmbientAir quality monitoring devices, not only becauseAQ Guard AmbientIt can overcome the harsh environment at sea and also meet the needs of experimental determination of mass concentration and particle size spectrum of atmospheric particles over the ocean due to its advantages in technical performance.

Faced with the harsh environment and various challenges of the ocean, the operation is simpleAQ Guard AmbientThe switch and switching interface can be controlled solely through the touch screen, and real-time monitoring data can be displayed. It can be used immediately upon power on, making it easy to carry and install.AQ Guard AmbientIt can also meet the requirements of precise measurement, with a time resolution of one data per second, meeting the experimental requirements for measuring particle data in a large space and range. At the same time, the casing installed behind the instrument fully protects it from direct exposure to the external environment, enhancing its safety against harsh environments. During the period20During several days of navigation experiments, it maintained a good working condition.

AQ Guard AmbientExpand technological possibilities

This experiment is also forPalas®Explore measurement methods that are different from the past. Prior to thisAQ Guard AmbientMainly used for fixed-point measurement, that is, placing the instrument in a fixed position for long-term monitoring. However, the data collection for this experiment was conducted by measuring the air flowing over the sea through navigation.AQ Guard AmbientIt is an optical observation instrument that is portable and easy to install. Therefore, at the beginning of the experiment, the researchers usedAQ Guard AmbientThe performance advantage lies inPalas®Propose ideas applicable to maritime observation.

AQ Guard AmbientThe outstanding performance validates the feasibility of the idea and is beneficial for expanding the futureAQ Guard AbmientThe usage scenarios for measurement. By moving, for exampleAQ Guard AmbientFixed on a ship or a mobile vehicle, the instrument can obtain particle measurement data over a larger spatial range as it moves.

AQ Guard AmbientThis ensures high-quality measurement results and smooth experimentation, providing technical support for the research, development mechanisms, and forecasting of marine atmospheric science.Palas®Not only did it play a crucial role in this research experiment, but it can also provide technical support in more fields in the future.
