Latest Ice and Temperature data

Latest Sea Ice and Global Temperature contents:

This automatically updated page has an embedded html window in which the numbers will appear. I'm planning to run the script at least once a day, at about 5.15 pm Japan time, when the JAXA ice numbers appear. It will check for the latest Had/UAH etc numbers. New numbers will appear bolded or colored. And the graphs will be updated.

This version has the additional 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 (1981-2010) 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.


Monthly global temperature anomaly data

Here is the latest global anomaly temperature data:

Here is the latest report from TempLS mesh weighted version:

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 active plotter for global temperature indices. You can vary the selection of plot data with the checkboxes. The legend is active; you can choose to draw linear regression lines, or to smooth the curves. You can also choose a new color by clicking on the color square next to the name. You can drag, stretch etc the plot - details are in this post

The plot also allows you to switch (toggle button "Trendback") to a mode which shows on the y-axis not the anomaly, but the trend from the x-axis time to the most recent data. All the same plotting facilities are there, except for regress.

Daily Reanalysis Temperature data

Here is the latest NCEP/NCAR reanalysis (see post) surface temperature (°C) anomaly area-weighted average for recent months, and for days of the current month.

Here is a WebGL active map of this year's daily temperatures. It has the usual trackball facilities. To get a specific day, let the mouse hover over the colored squares on the right; each square is a day, and the text top right tells you where you are. Click when you have the day that you want. Details are at this post.

NH and SH Sea Ice data

Here is the latest Arctic sea ice extent data. You can choose from JAXA Arctic Ice Extent, or from NSIDC NH or SH:


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.


And here is a log of the most recent data files to be posted:
