What does DHI mean in METEOROLOGY
Diffuse Horizontal Irradiance (DHI) is a measure of the light energy emitted by the sun that is scattered as it passes through the atmosphere. This scattered energy contributes to global irradiation, which is essential for all life on Earth. DHI, however, provides us with an exact quantum of the light energy received from the sun that has been scattered and diffused.
DHI meaning in Meteorology in Academic & Science
DHI mostly used in an acronym Meteorology in Category Academic & Science that means Diffuse Horizontal Irradiance
Shorthand: DHI,
Full Form: Diffuse Horizontal Irradiance
For more information of "Diffuse Horizontal Irradiance", see the section below.
Definition
Simply put, DHI refers to the diffuse horizontal irradiance, which is defined as “the radiant energy that reaches a given surface per unit area from a direct beam and from diffuse radiation after travelling over one horizontal distanceâ€. In other words, it is a measure of the total amount of sunlight scattered by air molecules before being dispersed upon a particular point or horizon.
Significance
The amount of diffuse horizontal irradiance reaching any given area on earth depends heavily upon geographic location and time of day or year. As such, monitoring DHI can be invaluable in understanding seasonal changes in solar power potential since solar resource assessments rely heavily on historical data regarding this type of irradiance. It's also important in photovoltaic systems design since it gives us information about expected sunshine intensity during any given period of time thereby helping to ensure optimal system performance throughout the year.
Essential Questions and Answers on Diffuse Horizontal Irradiance in "SCIENCE»METEOROLOGY"
What is Diffuse Horizontal Irradiance?
Diffuse Horizontal Irradiance (DHI) is the measure of solar energy that is diffused by the atmosphere and scattered in all directions onto a horizontal surface. This type of radiation provides illumination but not as much heat as direct sunlight
Final Words:
In conclusion, Diffuse Horizontal Irradiance (DHI) is an important factor when considering various factors related to solar radiation and its implications for things like system design and solar resource assessment over certain periods of time. Knowing how much DHI exists at any point in time allows us to make more accurate predictions about where we stand with respect to these topics, thereby ensuring proper design decisions for various projects and applications are made.
