This version has the aditional ice datasets and facilities described here.
Temperatures anomalies in the tables are as stated by the providers, with different anomaly bases. They have been converted to the same base (1979-2000) for plotting.
There is a new style of ice plot - an active plot where you can magnify sections.
The temperature and ice windows each have a current table at the top, with more data further down. There is also a log of datafile reporting dates, as explained here.
- JAXA Arctic Sea Ice Exrent. Various data periods
- Global Temperature indices - last four months
- Global Temperature indices - last four years
Sources: JAXA, HADCRUT4, GISS, UAH T2LT, RSS MSU, NOAA, NSIDC
Here is the latest global anomaly temperature data:
Here is the latest Arctic data. You can choose from JAXA Arctic Ice Extent, or from NSIDC NH or SH:
|JAXA Arctic||NSIDC NH||NSIDC SH||Enlarge|
And here is a log of the most recent data files to be posted:
Here is an active polar plot of the Jaxa Ice extent data. Units are million sq km. You can click on the current region circle to get a magnification, or on any sector to see that part expanded. Clicking on the legend marks the year in dark; clicking on the central picture makes it go away. Details here.
Here are some plots of temperature indices in recent times, set to a common anomaly base (1981-2010)
|Major temperature indices - last 5 months |
|Major temperature indices - last 4 years |
Here is an interactive user-scalable graph. You can drag it with the mouse horizontally or vertically. If you drag up-down to the left of the vertical axis, you will change the vertical scaling (zoom). Likewise below the horizontal axis.
