FAQ

Q1: What does "Four-Component" mean in a Four-Component Radiation Sensor? ❯

"Four-Component" refers to the sensor’s ability to measure four separate radiation components:

“Four-Component” refers to the sensor’s ability to measure four separate components of surface radiation: downward shortwave, upward shortwave, downward longwave, and upward longwave. These measurements together provide a complete characterization of the surface energy balance.

Q2: Why is a four-component sensor more advanced than a standard pyranometer? ❯

A standard pyranometer only measures shortwave radiation, while a four-component sensor captures both shortwave and longwave radiation in two directions. This enables detailed analysis of reflectance, emissivity, net radiation, and energy exchange between the surface and atmosphere.

Q3: Why is it important to measure both upward and downward radiation? ❯

Measuring upward and downward fluxes allows the sensor to calculate net radiation and albedo, assess heat exchange processes, and evaluate the surface–atmosphere energy budget with high accuracy.
