The QUIJOTE (Q-U-I JOint Tenerife) CMB Experiment is located at the Teide Observatory in Tenerife (Canary Islands). QUIJOTE consists of two telescopes and three instruments dedicated to measuring the polarized microwave sky between 10 and 40 GHz with degree angular resolution.

The QUIJOTE MFI (Multi-Frequency Instrument) wide survey covers the visible sky from the Teide Observatory (latitude 28.3 degrees) at elevations greater than 30 degrees. The first MFI data release in 2023 consists of 9000 h of observing time with three of the four QUIJOTE polarimeters between 2012 and 2018. Data products include Stokes IQU maps in channels centered at 11, 13, 17, and 19 GHz, as well as instrument model files including beam profiles and bandpasses, radio source catalogs, and component separated maps.
