Project idea
Evaluate the response of the middle atmosphere to the short term solar UV irradiance variability
Evaluate the response of the middle atmosphere to the short term solar UV irradiance variability
Goals• Find out how well we understand
the solar influence on the middle atmosphere;
• Learn how to manage near-real-time operation;
• Space Weather Service is secondary goal but may become interesting if successful !
• Preparatrion to the model extention to upper atmosphere

Ozone and hydroxyl response to the solar variability
January 2004 case study
Hydroxyl and ozone in the mesosphere simulated with CCM SOCOL. These components are sensitive to variable solar irradiance becauseH2O + hv (121.5 nm) => OH + H OH goes up O3 + OH => O2 + HO2 O3 decreases

Solar spectrum reconstructionWe have reconstructed solar UV irradiance for 120-680 nm required by the model from LYRA data applying linear regression analysis. We use the following formula for the reconstruction:
Fi= A + B Pi
F is solar spectral UV irradiance; is wavelength; i is day number; A and B correlation coefficients calculated SOLSTICE/SORCE and SIM/SORCE for 2008; P is solar irradiance from LYRA (Channel 2).
See Egorova et al. (ACP, 2008) for details and accuracy estimation

1.Ozone, hydroxyl, electron and ion densities show some response to the solar irradiance variability
2.Lyra data can be used for nowasting! If available in RT mode
3.Some problems with data and model remain ...
