SUMMARY:Cosmic Microwave Background observations 
DESCRIPTION:Cosmic Microwave Background observations \nDr. Ricardo Tanausu 
 Génova Santos\n\nIn the first part of this talk I will present a historic
 al review of the CMB observations, one of the most powerful cosmological p
 robes. Following the first talk of this series, where Jose Alberto describ
 ed the basic parameters that define the standard cosmological model, I wil
 l here summarize the constraints to these parameters that have been derive
 d from these observations. I will also describe the current challenges in 
 this field, in particular the detection of the inflation's B-mode signal t
 hrough CMB polarization observations, as well as the experiments that have
  been developed worldwide to this aim, including IAC's QUIJOTE.  In the se
 cond part, I will focus on the so-called ``missing baryon problem'', i.e. 
 the fact that the half of the expected baryon content of the local univers
 e remains yet undetected. I will describe the theoretical studies that pro
 vide hints on where these baryons could be located, and the observational 
 efforts that have been undertaken in this regard.
