代码：

Map.centerObject(ee.Geometry.Point([34.24726, 1.07711]), 16);

var s2_img_1c = ee.Image('COPERNICUS/S2_HARMONIZED/20220126T075211_20220126T075213_T36NXG');

var s2_img_2a = ee.Image('COPERNICUS/S2_SR_HARMONIZED/20220126T075211_20220126T075213_T36NXG');

Map.addLayer(s2_img_1c, {bands:['B4', 'B3', 'B2'], min: 0 , max: 2000}, '1c');

Map.addLayer(s2_img_2a, {bands:['B4', 'B3', 'B2'], min: 0 , max: 2000}, '2a');

第一个是COPERNICUS/S2的数据IC数据

第一个是COPERNICUS/S2的数据2a数据

不难看出2A数据更清晰和色彩更明艳
