First PICARD workshop

 

 

 

 

 

 

 

This workshop is dedicated to the solar activity and specifically to two thema

1) the understanding of the ORIGINS of the solar variability

2) the determination of the SOLAR INDICATORS that could influence the chemistry of the Earth atmosphere

Some first examples of interaction will be also presented
