Weekly and Biweekly time series for tundra regions 1982-2011
Listed in NASA Earthdata CMR
Time series for weekly surface temperature (full tundra) and sea ice concentration (100-km) for each Treshnikov domain comprises this seasonal data set.
Description
The time series for biweekly (twice a month) MaxNDVI for the 23 Treshnikov domains are in this data set. The data cover the period from 1982-2011.
The data text files are tab delimited and column names identify the week of the year and (See main README for abbreviations and see TreshnikovJan11.png). 23 files for each of the three fields for example: beauf_MaxNDVI_biweekly_82-11_ftun.txt, beauf_seaice_weekly_82-11_100km.txt, and beauf_ts_weekly_82-11_ftun.txt This file contains data for the Beaufort region and has 100-km series for spring sea ice concentration and full tundra average for MaxNDVI and surface temperature (ts).

Each of the 23 Treshnikov divisions (defined using Jan 2011 map) has a similar format to these files. A value of 999 signifies missing data.
