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):
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.
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.
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:
