In support of the NOAA Arctic Research Program Distributed Biological Observatory (DBO), which is a multi-agency program in the Arctic, color images of daily and weekly satellite data are provided together with time series animation of the key variables. The data presented are weekly averages of most recent data for the following:

(1) Chlorophyll Pigment Concentration; (2) Sea Surface Temperature (SST); (3) Sea Ice Concentration; (4) Cloud Fraction; (5) Winds and Sea Level Pressure (SLP); (6) Sea Surface Salinity (SSS); and (7) Sea Surface Height Anomaly (SSHA). Chlorophyll, SST, and cloud data are from MODIS while sea ice concentration data are from SSM/I and winds and SLP data are from NCEP reanalysis. SSS nine-day average is from SMOS, and the SSHA is from Jason-2. Also presented are animations of running averages of weekly chlorophyll pigment concentration, daily surface temperatures using Reynolds SST data and daily ice concentration with NCEP winds. The five boxes in the images are the DBO study sites.

 If you are interested in seeing more imagery or obtaining the historical data, please contact Josefino Comiso for further information.

Ice Concentrations with Ten Meter Wind Flows

Animation of Sea Ice Concentration

An animation of the daily sea ice concentration with wind flows derived from NCAR/NCEP 10 meter U and V wind vectors. This animation demonstrates the changing winds and the effect that the winds have on the sea ice concentration in the Northern Hemisphere. Longer lines mean faster flows.

Recent Chlorophyll Pigment Concentration

Animation of Recent Chlorophyll Density

An animation which demonstrates the latest satellite data given for chlorophyll pigment concentration. Each image is a seven day average of the available data at the time the image was created. The most recent seven day average is given in Figure 1.

 

Daily SST

Animation of Daily SST

An animation using daily averages of the NOAA NCDC high resolution SST for 21 days.

 

Weekly Chlorophyll Pigment Concentration

Image of Weekly Chlorophyll Density

Figure 1: This image is derived from the daily level-3 MODIS AQUA data set for chlorophyll pigment concentration (mg/m3). This image represents a seven day average of the most current data. The dates are given in the upper right corner.

Weekly Cloud Fraction

Image of Weekly Cloud Fraction

Figure 4: The cloud fraction is compiled from the level-2 MODIS AQUA cloud mask data set, MYD35. A cloud cover of 100 percent is the brightest red. The dates that are used are shown in the upper right corner.

Daily Surface Level Pressure and Wind Vectors

Image of Surface Pressure and Wind Vectors

Figure 5: The surface level pressure is shown in conjunction with the wind vectors for the Arctic. Both sets of data are derived from NCEP Reanalysis Daily Averages.

Recent Sea Surface Salinity (SSS)

Animation of Recent Chlorophyll Density

Figure 6: The SMAP-SSS image is created by projecting the 8-Day running mean global data set onto the SSM/I grid using a bilinear interpolation algorithm.

Weekly Sea Surface Height Anomaly (SSHA)

SSHA Image

Figure 7: The SSHA image uses the orbital GPS-based Operational Geophysical Data Record (GPS-OGDR-SSHA) for OSTM/Jason-3 that is generated by the Orbiter and Radio Metric Systems group at JPL. The image represents a weekly average of the orbits for the dates that are shown at the top right of the image. The traces are enlarged for visibility.
