Tutorial 6.2

2.3. Functions defined

Below code snippet define two functions

• To get number of days in a month
• To convert mm/hour to mm/month

//////FUNCTIONS DEFINED////////

 

//below function return number of days in a month

function getDaysInMonth(y,m) {

  var dt = ee.Date.fromYMD(y,m,1);

  var n = dt.advance(1,"month").difference(dt,'day');

  return n;

}

 

//below function will convert mm/hr to mm/month for the 

// GPM data

var monthly = function(image) {

  var dt = ee.Date(image.get("system:time_end"));

  var y = dt.get('year');

  var m = dt.get('month');

  var days = getDaysInMonth(y,m);

  return image.multiply(days).multiply(24).copyProperties(image, ["system:time_start", "system:time_end"]);

};
