    <description descriptionType="Abstract">&lt;p&gt;In our on-going effort to characterize M dwarfs, we have carried out multi-band photometry calibrations of metallicity for early and intermediate M dwarfs using Gaia EDR3, 2MASS and AllWISE. These catalogs, combined with a sample of 5435 M dwarfs with additional parameters determined by APOGEE high-resolution spectroscopy, allow us to study the effect of the chemical composition in color-color and color-magnitude diagrams. We train the calibrations using Bayesian statistics and Markov Chain Monte Carlo (MCMC) techniques and derive several photometric calibrations aplicable to M dwarfs with metallicities of -0.4 &amp;le; [Fe/H] &amp;le; +0.4, obtaining estimations reliable to 0.10 dex. Lastly, we compare our results with previous photometric studies of metallicity for an additional sample of FGK+M common-proper-motion systems, finding a great predictive performance.&lt;/p&gt;</description>
