Solar radiation trend across China in recent decades: a revisit with quality-controlled data
Solar radiation China recent decades quality-controlled data
2011/1/14
Solar radiation is one of the most important factors affecting climate and environment, and its long-term variation is of much concern in climate change studies. In the light of the limited number of ...
A new method for deriving aerosol solar radiative forcing and its first application within MILAGRO/INTEX-B
aerosol solar radiative forcing first application MILAGRO/INTEX-B
2010/8/24
We introduce a method for deriving aerosol spectral radiative forcing along with single scattering albedo, asymmetry parameter, and surface albedo from airborne vertical profile measurements of shortw...
Energetic particle precipitation in ECHAM5/MESSy – Part 2: Solar proton events
Energetic particle precipitation ECHAM5/MESSy Solar proton events
2010/8/6
The atmospheric chemistry general circulation model ECHAM5/MESSy (EMAC) has been extended by processes that parameterize particle precipitation. Several types of particle precipitation that directly a...
Analysis of global and regional CO burdens measured from space between 2000 and 2009 and validated by ground-based solar tracking spectrometers
global and regional CO burdens ground-based solar tracking spectrometers
2010/4/16
Interannual variations in AIRS and MOPITT retrieved CO burdens are validated, corrected, and compared with CO emissions from wild fires from the Global Fire Emission Dataset (GFED2) inventory. Validat...
Solar cycle signals in sea level pressure and sea surface temperature
Solar cycle signals sea level pressure sea surface temperature
2010/3/31
We identify solar cycle signals in 155 years of global sea level pressure (SLP) and sea surface temperature (SST) data using a multiple linear regression approach. In SLP we find in the North Pacific ...
27-day variation in cloud amount in the Western Pacific warm pool region and relationship to the solar cycle
Western Pacific warm pool region solar cycle
2010/2/15
Although linkages between solar activity and the earth's climate have been suggested and the 11-year cycle in solar activity evident in sunspot numbers is the most examined example of periodicity in p...
Technical Note: Time-dependent limb-darkening calibration for solar occultation instruments
Time-dependent limb-darkening calibration solar occultation instruments
2010/1/18
Solar occultation has proven to be a reliable technique for the measurement of atmospheric constituents in the stratosphere. NASA's Stratospheric Aerosol and Gas Experiments (SAGE, SAGE II, and SAGE I...
Particulate absorption of solar radiation: anthropogenic aerosols vs. dust
Particulate absorption solar radiation anthropogenic aerosols vs. dust
2009/6/22
Particulate solar absorption is a critical factor in determining the value and even sign of the direct radiative forcing of aerosols. The heating to the atmosphere and cooling to the Earth's surface c...
Technical Note: Feasibility of CO2 profile retrieval from limb viewing solar occultation made by the ACE-FTS instrument
CO2 profile solar occultation ACE-FTS instrument
2009/5/6
Major limitations of our present knowledge of the global distribution of CO2 in the atmosphere are the uncertainty in atmospheric transport mixing and the sparseness of in situ concentration measureme...
The effect of the solar rotational irradiance variation on the middle and upper atmosphere calculated by a three-dimensional chemistry-climate model
solar rotational irradiance variation atmosphere three-dimensional chemistry-climate model
2009/3/12
This paper analyzes the effects of the solar rotational (27-day) irradiance variations on the chemical composition and temperature of the stratosphere, mesosphere and lower thermosphere as simulated b...
The part of the solar spectrum with the highest influence on the formation of SOA in the continental boundary layer
solar spectrum SOA continental boundary layer
2009/3/12
The relationship between nucleation events and spectral solar irradiance was analysed using two years of data collected at the Station for Measuring Forest Ecosystem-Atmosphere Relations (SMEAR II) in...
Impact of large solar zenith angles on lower stratospheric dynamical and chemical processes in a coupled chemistry-climate model
large solar zenith angles lower stratospheric dynamical chemical processes coupled chemistry-climate model
2009/3/11
Actinic fluxes at large solar zenith angles (SZAs) are important for atmospheric chemistry, especially under twilight conditions in polar winter and spring. The results of a sensitivity experiment emp...
Major solar eruptions (coronal mass ejections) are accompanied by massive ejections of protons. When these charged particles head for the Earth through the interplanetary magnetic field with high flux...
