Summary
This study introduces high-time resolution emission profiles for atmospheric pollutants and greenhouse gases. These new temporal profiles improve atmospheric modeling and decision-making by capturing hourly variations in human activity emissions.
Area of Science:
- Atmospheric Chemistry and Physics
- Environmental Science
- Climate Science
Background:
- Human activities cause atmospheric emissions with significant temporal variations, from hourly to inter-annual scales.
- Current yearly emission calculations often fail to represent critical pollution episodes, seasonal patterns, or time-dependent atmospheric processes.
- Accurate temporal emission data is crucial for atmospheric modeling, Earth observation, and informed policy decisions.
Purpose of the Study:
- To develop high-time resolution temporal profiles for air pollutants and greenhouse gases emitted by anthropogenic sources.
- To support atmospheric modeling, Earth observation, and decision-making processes with detailed emission data.
- To create a harmonized emission temporal distribution applicable to various emission databases.
Main Methods:
- Development of country/region- and sector-specific yearly profiles for all emission sources.
- Creation of time-dependent yearly profiles for sources exhibiting inter-annual variability in seasonal patterns.
- Generation of country-specific weekly and daily profiles to accurately represent hourly emissions.
- Implementation of a flexible system for computing hourly emissions, incorporating diverse user inputs.
Main Results:
- Introduction of novel temporal profiles for the Emissions Database for Global Atmospheric Research (EDGAR).
- Establishment of country/region- and sector-specific yearly, weekly, daily, and hourly emission distributions.
- Development of a system enabling the computation of hourly emissions with user-defined inputs.
- Creation of a harmonized temporal emission dataset for atmospheric modeling.
Conclusions:
- The developed high-time resolution emission profiles enhance the accuracy of atmospheric modeling and Earth observation.
- These profiles provide crucial data for understanding and mitigating the impacts of air pollution and climate change.
- The harmonized temporal distribution promotes consistency and comparability in atmospheric research and policy evaluation.

1.6K
Protons bonded to heteroatoms such as nitrogen and oxygen exhibit a range of chemical shift values. This is due to the varying degree of hydrogen bonding between the proton and the heteroatom in other molecules. The extent of hydrogen bonding affects the electron density around the proton, thereby giving different chemical shift values for the protons in the proton NMR spectrum.

When solids, liquids, or condensed gases are heated sufficiently, they radiate some of the excess energy as light. Photons produced in this manner have a range of energies, and thereby produce a continuous spectrum in which an unbroken series of wavelengths is present.

3.3K
Atomic emission spectroscopy (AES) is an analytical technique used to determine the elemental composition of a sample by analyzing the light emitted from excited atoms. In AES, atoms in a sample are excited to higher energy levels by thermal energy from high-temperature sources, such as plasma, arcs, or sparks. When these excited atoms return to lower energy states, they emit light at specific wavelengths characteristic of each element. The resulting atomic emission spectrum, which consists of...

2.2K
The resolution of a mass spectrometer depends on the efficiency of separating ions with different ion masses. The mass of an atom is approximated to the sum of the masses of protons and neutrons inside, considering the masses of protons and neutrons as equal. However, the masses of the proton (1.6726 × 10−24 g) and neutron (1.6749 × 10−24 g) are not truly equal. There is a minor error in the expression of atomic masses relative to the simplest atom of hydrogen. For...

Inductively coupled plasma (ICP) is the common plasma source used in atomic emission spectroscopy (AES), a technique that detects and analyzes various elements in a sample. This method is often called inductively coupled plasma atomic emission spectroscopy (ICP-AES).
There are three main types of inductively coupled plasma atomic emission spectroscopy (ICP-AES) instruments: sequential, simultaneous multichannel, and Fourier transform instruments, with the latter being less commonly used....

In atomic emission spectroscopy (AES), high-temperature atomizers excite a broad range of elements and molecules that generate complex emissions from sources such as oxides, hydroxides, and flame combustion products in the flame or plasma. Several strategies can be employed to minimize spectral interferences caused by overlapping emission lines or bands. These include increasing instrument resolution, choosing alternative emission lines, optimally placing the detector in low-background regions,...
