The COVID-19 pandemic has forced most countries in the world to adopt strict policies of social isolation. As a consequence, there have been positive and negative indirect effects on the environment. For example, some countries have reported improvements in air quality, cleaner beaches, and decreased environmental noise. However, there have also been negative indirect effects. This research aims to analyze the effects of social isolation policies on meteorological observation systems. It was found that the meteorological observations from aircraft as well as surface-based observations have been strongly affected. To a lesser extent, marine and satellite measurements have been affected. Our research highlights the importance of having a resilient and automated meteorological observation system, as well as complementary methods of monitoring the atmosphere and weather.

Abstract The paper covers the important topic of rotor–stator propulsor system design and operation. For the stand-alone marine screw propeller, both the design criteria for loading distribution and the theoretical efficiency limits are well described in the basic literature. This is in contrast to the combined propulsor system like a propeller cooperating with a pre-swirl device. The paper describes the current state of the art, summarising results obtained by various researchers by installing energy-saving devices on particular vessels. The design methods utilised are briefly outlined, with the main characteristics underlined. Rough analysis of the gathered data confirms the expected trend that a higher efficiency gain due to ESD installation is possible for a higher propeller loading.
