生成图表时出错：超出了Google Earth引擎中显示的用户内存限制

如何解决生成图表时出错：超出了Google Earth引擎中显示的用户内存限制

该代码无法正常工作，并且在生成过去20年格陵兰岛地表温度趋势的时序图时显示错误生成图。

var dataset = ee.FeatureCollection('USDOS/LSIB_SIMPLE/2017')
var greenBorder = dataset.filter(ee.Filter.eq('country_na','Greenland'));

print(greenBorder);
Map.centerObject(greenBorder,4);
Map.addLayer(greenBorder);
var start = ee.Date('2000-01-01')
var end = ee.Date('2019-12-31')
var daterange = ee.Daterange(start,end);
var mod11a2 = modis.filterDate(daterange);
var modLSTday = mod11a2.select('LST_Day_1km');

print(modLSTday)
var modLSTc = modLSTday.map(function(img) {
  return img
    .multiply(0.02)
    .subtract(273.15)
    .copyProperties(img,['system:time_start']);
});


var ts1 = ui.Chart.image.series({
 imageCollection: modLSTc,region: greenBorder,reducer: ee.Reducer.mean(),scale: 10000,xProperty: 'system:time_start'})
 .setoptions({
 title: 'LST 2015 Time Series',vAxis: {title: 'LST Celsius'}});
 
print(ts1);
