23 MICO Modelo Ionosférico Colombiano - First approach to develop a model -

24 MICO (macaco or monkey ) Ionospheric Colombian Model

25 We developed a model to provide information of TEC in the ionosphere

26 Slant TEC Pseudorange Carrier phase Observation files

27 Estimation of orbits Navigation files

28 Comparison with other models

29 MICO Behaviour of TEC variations CME on June 4th 2011
