NSIDC has obtained data from the DMSP F-18 satellite and is in the process of intercalibrating the F-18 data with F-17 data. Intercalibration addresses differences between the series of sensors, in order to provide a long-term, consistent sea ice record. While this work continues, we are displaying the uncalibrated F-18 data in the daily extent image. The daily time series graph shows F-17 data through March 31, and F-18 data from April 1 forward. Initial evaluation of the uncalibrated F-18 data indicates reasonable agreement with F-17, but the data should be considered provisional and quantitative comparisons with other data should not be done at this time.

The dashed green line represents sea ice extent for the record low-ice year of 2012.

If the new, intercalibrated data eventually confirms the apparent dropping ice levels, I am sure the denialist community will simply dismiss it as alarmist nonsense (or an outright fabrication) from the global warming hoaxsters.

If the new, massaged data shows a more optimistic result, they will seize on it as absolute proof that the Arctic ice is rebounding. Stay tuned to this channel for further reports.
