Tropical cyclones 1848 – 2014 active and online!

16 January 2015   //   by admin   //   Data, News  //  Comments (0)
Climate Wikience now provides best tracks for all tropical cyclones since 1848 up to 2014. The data were imported from “IBTrACS – best tropical cyclone tracks”
Climate Wikience enables you not only to view tracks on the globe but also visualize related data like wind speed or cloud top temperature.

The track display is interactive. You can change the time for which related data are visulized simply by double-clicking on cyclone center. Climate Wikience will automatically change the time and loads the data.
Each cyclone center has associated data like latitude/longitude coordinates, the date and time and many other properties. You can visualize the associated data near cyclone center by adjusting the “Properties” tab.

Isolines for satellite data

16 January 2015   //   by admin   //   Data, News  //  Comments (0)
Now Climate Wikience displays isolines for satellite data. Until now, Climate Wikience was able to display isolines only for data without missing values like climate reanalysis. However, satellite measurements often have areas without data due to clouds or other reasons. Improved algorithm of Climate Wikience now draws isolines for data with missing values.

Below are examples of visualizing isolines for satellite data.

You can label any isoline at its arbitrary point. Simply enable “Click for value” option at the “Properties tab”. A label with isoline value will appear at the point where you clicked on the isoline. Click on the isoline again to hide the label.
Zoom over South America with several labeled isolines and increased width of isolines (compare “Properties tab” of this image and the one below).
