【Data Scraping Field】Outgoing Longwave Radiation (OLR)

Outgoing Longwave Radiation (OLR) is a key indicator in meteorology and climatology, representing the amount of energy absorbed by the Earth's surface and atmosphere that is emitted as infrared radiation into space.

【Data Scraping Field】Net Radiation

Net radiation refers to the difference between all incoming radiation energy received by the Earth's surface and the radiation energy emitted from it.

【Data Scraping Field】Scattering Radiation

Scattering radiation refers to the phenomenon where radiative energy (primarily electromagnetic radiation) interacts with molecules, aerosols, particles, or atoms in the atmosphere or within materials, causing its propagation direction to change while being redistributed.

【Data Scraping Field】Reflected Radiation

Reflected radiation refers to the electromagnetic energy emitted from sources such as the sun or artificial lighting that, after reaching the surface of the ground or an object, is not absorbed but is instead reflected back outward.

【Data Scraping Field】Direct Solar Radiation

Direct solar radiation refers to the parallel rays of sunlight that reach the Earth's surface without being scattered by the atmosphere. Its intensity is jointly determined by factors such as the solar elevation angle, atmospheric transparency, cloud cover, and altitude.

【Data Scraping Field】Solar Radiation

Solar Radiation refers to the total energy released by the sun that propagates through space in the form of electromagnetic waves and ultimately reaches the Earth.

【Data Scraping Field】UV Index (Ultraviolet Index)

UV Index (Ultraviolet Index) is an international metric that quantifies the intensity of ultraviolet (UV) radiation reaching the Earth's surface from the sun.

【Data Scraping Field】Evaporation

Evaporation refers to the total amount of water that enters the atmosphere from the Earth's surface (water bodies, soil, vegetation, etc.) through evaporation within a certain period of time (such as day, month, year). It is usually measured in millimeters (mm) and is measured using tools such as evaporation pans, weather stations, or remote sensing satellites. It is an important indicator reflecting the regional water cycle, drought level, and water resource sustainability.

【Data Scraping Field】Snowfall

Snowfall is measured in millimeters by melting snow collected over 12 or 24 hours in a standard container. It reflects the intensity of snowfall water. The classification is strict: 0.1-2.4 mm of snowfall in 24 hours is considered light snow, 10.0-19.9 mm is blizzard, and over 30 mm is extremely heavy blizzard.

【Data Scraping Field】Rainfall Intensity (Precipitation Intensity)

Rainfall Intensity refers to the amount of precipitation per unit time, usually in millimeters per hour (mm/h) or millimeters per day (mm/d), reflecting the severity of precipitation. According to intensity, it can be divided into light rain, moderate rain, heavy rain, rainstorm and other different levels.
