GRACE satellite Greenland data is too negative-biased

Despite the DMI institute showing quite a mass gain for Greenland in 2016:

..The GRACE satellite data showed a continued mass decline.

New improved Australia RSS TLT satellite temperature

In my first attempt at this I got the longitude wrong (details here). Having corrected that, in my second attempt I defined a smaller rectangle to avoid any ocean areas as shown in the graph that follows.

...which yields the graph (16-point moving average in red):

More RSS TLT temps

It's often said there's a lot of warming in the North Atlantic & surrounding land stations so let us check there first with the RSS TLT temps in a square as depicted in the following map:

There is some warming in excess of the global average. It looks similar to the temps for North latitudes 21.25 N to 36.25 N (see graphs further down). In red is the code for Matlab R2016a.

RSS satellite temperature for Australia/Pacific

Below are RSS satellite temperatures for various regions in Australia/Pacific.  In a previous post (here) I derived lower tropospheric temp for Australia in a rectangle shown in the map below.

In this post I define a smaller rectangle (red) to avoid any ocean areas, between longitudes 123.75 E to 146.25 E and latitudes 31.25 South to 21.25 South.

RSS temp anomaly for Australia corrected for longitude

I've discovered a mistake in my first attempt at unlocking the RSS temperature file for lower tropospheric temps: my longitude was off by 180 degrees.

Some time around that first attempt I took the time to verify the latitude (described here) but not the longitude. I discovered my mistake when I decided to verify the longitude for an upcoming post. Here is how the latitude and longitude numbers in the 144 x 72 x 458 array should look on a world map:
