var ic = ee . ImageCollection ( 'COPERNICUS / S2_SR ');
// Filter the images to those that intersect Mount Shasta for 3 months
// in 2019 and 2021 (two image collections).
var geom = ee . Geometry . Point ( - 122.196 , 41.411 );
var ic2018 = ic . filterBounds ( geom ). filterDate ( '2019 - 07 - 01 ', '2019 - 10 - 01 ');
print ( '2018 image collection ', ic2018 );
var ic2021 = ic . filterBounds ( geom ). filterDate ( '2021 - 07 - 01 ', '2021 - 10 - 01 ');
print ( '2021 image collection ', ic2021 );
// Merge the two image collections.
var icMerged = ic2018 . merge ( ic2021 );
print ( 'Merged image collection ', icMerged );
