Landsat 8 truecolor gif con Google Earth Engine

 Una prova di LandSat 8 truecolor con Google Earth Engine...stavo cercando i periodi con neve su questo settore dell'Appennino ma non e' mi e' stato molto di aiuto (il periodo va da agosto 2013 a agosto 2022....28 immagini con lista completa al termine del post)

var geometry = 
    /* color: #d63000 */
    /* displayProperties: [
      {
        "type": "rectangle"
      }
    ] */
