Radiation: Applications

1.6K
The average temperature of Earth is the subject of much current discussion. Earth is in radiative contact with both the Sun and dark space; it receives almost all its energy from the radiation of the Sun and reflects some of it into outer space. Dark space is very cold, about 3 K, so Earth radiates energy into it. For instance, heat transfer occurs from soil and grasses, the rate of which can be so rapid that frost can occur on clear summer evenings, even in warm latitudes.

Mechanisms of Heat Transfer II

4.1K
In convection, thermal energy is carried by the large-scale flow of matter. Ocean currents and large-scale atmospheric circulation, which result from the buoyancy of warm air and water, transfer hot air from the tropics toward the poles and cold air from the poles toward the tropics. The Earth’s rotation interacts with those flows, causing the observed eastward flow of air in the temperate zones. Convection dominates heat transfer by air, and the amount of available space for the airflow...

Conduction, Convection and Radiation: Problem Solving

2.1K
There are three methods by which heat transfer can take place: conduction, convection, and radiation. Each method has unique and interesting characteristics, but all three have two things in common: they transfer heat solely because of a temperature difference; and the greater the temperature difference, the faster the heat transfer.
In order to solve a problem related to heat transfer, first of all, the situation needs to be examined to determine the type of heat transfer involved. This could...

Random Error01:04

Random Error

7.5K
Random or indeterminate errors originate from various uncontrollable variables, such as variations in environmental conditions, instrument imperfections, or the inherent variability of the phenomena being measured. Usually, these errors cannot be predicted, estimated, or characterized because their direction and magnitude often vary in magnitude and direction even during consecutive measurements. As a result, they are difficult to eliminate. However, the aggregate effect of these errors can be...

Area of Science:

  • Human biometeorology
  • Atmospheric sciences
  • Environmental modeling

Background:

  • Estimating mean radiant temperature (MRT) in outdoor environments is a significant challenge in human biometeorology.
  • Existing methods often lack global scale applicability or require extensive observational data.

Purpose of the Study:

  • To present a general framework for computing global-scale MRT for human subjects in outdoor settings.
  • To integrate solar and thermal radiation data from numerical weather prediction (NWP) models into MRT estimation.

Main Methods:

  • Developed a framework utilizing radiation fluxes (direct and diffuse solar and thermal) from NWP models.
  • Incorporated solar position variations impacting radiation components.
  • Generated gridded, globe-wide MRT maps.

Main Results:

  • Successfully computed global MRT distributions using European Centre for Medium-Range Weather Forecasts (ECMWF) reanalysis data.
  • Demonstrated good agreement between NWP-based MRT and ground-based measurements (R² > 0.88, bias = 0.42°C).

Conclusions:

  • The proposed framework offers a viable method for large-scale MRT estimation.
  • NWP-based MRT can serve as a valuable proxy for direct observations in various application studies.
