Resumen:
Immediately after launch the six COSMIC satellites orbited in very close proximityfor a few months, so during this period the data was particularly clustered ingeographical areas and time.This offered an excellent opportunity to evaluate the precision of the retrievedprofiles through the use of nearly collocated and simultaneous observations.The idea is not new. It has been mainly used in the neutral atmosphere. In theionosphere it has been applied to earlier product versions, which later wereimproved or corrected.This study uses the most newly post-processed data (version 2010.2640) providedby CDAAC (COSMIC Data Analysis and Archive Center). We statistically evaluatedthe precision of GPS radio occultations (RO) in the ionosphere by using the level 2 electron density product.
