How can I extarct mean of each image collection in google earth engine?
for example for this code:
var modis = ee.ImageCollection("MODIS/006/MOD13Q1")
.filterBounds(geometry)
.filterDate("2000-01-01","2001-01-01")
.select("NDVI");
print(modis)
var mod13 = modis.map(function(img){
return img.multiply(0.0001)
.copyProperties(img,['system:time_start','system:time_end']);
});

Earth Engine provides very nice functionality to calculate statistics on imagery called reducers. There are plenty of ways to use reducers but as simple examples you can calculate the statistics at the pixel level or provide a geometry to calculate statistics:
I hope this helps!
