GEE下载MODISA1LST

GEE下载MODISA1LST是指使用Google Earth Engine (GEE) 下载MODIS/006/MOD11A1中的地表温度数据。可以使用以下代码示例来下载该数据：

var geometry = ee.FeatureCollection('users/www1573979951/luyixian');
Map.centerObject(geometry, 7);
var modis = ee.ImageCollection('MODIS/006/MOD11A1');
var modisLST = modis.filterBounds(geometry).filterDate('2021-01-01', '2021-12-31').select('LST_Day_1km');
modisLST = modisLST.map(function(img){
  var date = img.get('system:time_start');
  return img.multiply(0.02).subtract(273.15).set('system:time_start', date);
});
print(modisLST);
Map.addLayer(modisLST.mean().clip(geometry), {min: 10, max: 30, palette: ['green', 'yellow', 'red']}, 'LST');

这段代码可以获取指定日期范围内的MODIS地表温度数据，并将其转换为摄氏度。最后，代码会将地表温度数据以图层形式添加到地图上，使用绿色、黄色和红色调色板表示温度范围为10到30摄氏度。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
