| Zusammenfassung |
| An updated version (Version 3) of the Snow Melt Onset Over Arctic Sea Ice
from SMMR (Scanning Multichannel Microwave Radiometer) and SSM/I-SSMIS (Special Sensor Microwave/Imager-Special Sensor Microwave Imager/Sounder)
Brightness Temperatures data set is now available. The data
record has been reprocessed and extended to cover the years 1979–2012. From
this data set, a statistical summary of melt onset (MO) dates on Arctic sea
ice is presented. The mean MO date for the Arctic Region is 13 May (132.5 DOY – day of year)
with a standard deviation of ±7.3 days. Regionally, mean MO
dates vary from 15 March (73.2 DOY) in the St. Lawrence Gulf to 10 June
(160.9 DOY) in the Central Arctic. Statistically significant decadal trends
indicate that MO is occurring 6.6 days decade−1 earlier in the year for
the Arctic Region. Regionally, MO trends are as great as −11.8 days decade−1
in the East Siberian Sea. The Bering Sea is an outlier and MO
is occurring 3.1 days decade−1 later in the year. |
