Has the hockey schtick left the building?


Unfortunately we may never know the real identity of who the hockey schtick is. They have protected their anonymity well. And no blame there. Why would't you protect your anonymity online? You have every right to. The only thing I can gather from their blog is that their initials are  "MS". But who knows if that's even valid?

Hockey Schtick appears to be a chemical engineer by trade who last blogged on Feb 4 2017. Lately their twitter feed appears to have been hacked.

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.

Naughty BoM uptweaking Australia average temperature



Below is my derived RSS satellite temperature for Australia in the following rectangle:

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:
