Weather conditions refer to the atmospheric and climatic conditions in a specific place and time. The main weather conditions include:
- Temperature: Temperature is the measure of the amount of heat in the air. It is measured in degrees Celsius or Fahrenheit.
- Precipitation: Precipitation is the amount of water that falls from the sky, whether in the form of rain, snow, hail or sleet.
- Humidity: Humidity is the amount of water vapor in the air. It is measured in percentage of relative humidity.
- Wind: Wind is the movement of air. It is measured in kilometers per hour or miles per hour.
- Atmospheric pressure: Atmospheric pressure is the force that air exerts on the Earth’s surface. It is measured in millibars or inches of mercury.
- Visibility: Visibility is the distance at which one can see clearly. It is measured in kilometers or miles.
These weather conditions can vary significantly from one place to another, even within the same city or region. Additionally, they can change rapidly due to factors such as the time of day, the season, altitude, and proximity to bodies of water.
Influence on remote sensing
Weather conditions have a significant influence on remote sensing, which is the technology used to obtain information about the Earth from satellites and other airborne platforms. Some examples of how weather conditions can affect remote sensing include:
- Clouds: Clouds can block the satellite’s view and make image capture difficult. If the cloud cover is too dense, important details can be lost.
- Fog: Fog reduces visibility and makes images blurry or unclear.
- Precipitation: Rain or snow can interfere with the satellite signal and affect image quality.
- Wind: Wind can move clouds or atmospheric layers and alter image quality.
- Humidity: Humidity can affect the quality of the satellite signal and the accuracy of measurements.
- Temperature: Temperature influences the amount of water vapor in the air, which in turn affects image quality.
In general, ideal weather conditions for remote sensing are clear days with little cloud cover and no precipitation. However, there are techniques and algorithms that allow for correction or minimization of adverse weather effects, and that allow for useful information about the Earth to be obtained under a wide variety of conditions.
