Site/Hive Description:

Hive is located in a suburban neighborhood about 5 miles south of Indianapolis. It is an area of flat glacial till, with small patches of woods surrounding a nearby creek. The hive is in full sun at least 50% of the day.

Hive was started in April of 2010 with two deep hive bodies for brood, screened bottom board, queen excluder, and a medium super.

The colony is Italian, with a 2-3 year old queen from an observation hive combined with two colonies that had survived the winter but were queenless.

The scale is a Fairbanks & Morse metric 150Kg capacity platform scale. It is leveled on concrete cinder block base and has 10gram increments on a slider bar. The scale is calibrated - 420g counterpoise and with 1g masses as additional weights.

MODIS Subset Data (from the ORNL DAAC)
Red dots are the average of all pixels with acceptable quality (see landcover extract below for area covered).
Blue dots are the center pixel only (point is not plotted if the pixel is of unacceptable quality).

 

 

NDVI

The Normalized Difference Vegetation Index (NDVI) is the ratio of the  difference between visible (red) and infra-red (IR) wavebands to the sum of these bands. 

NDVI = nir - red / nir + red


 NDVI provides an indication of the amount and vigor of vegetated  surfaces. 

 NDVI has been widely used with multiple generations of satellite data.

EVI

 The Enhnaced Vegetation Index (EVI) is a more complicated combination of wavebands compared to the more widely used index, NDVI.  The advantage of this newer index is improved sensitivity in high biomass regions and reduction in atmospheric influences.
where,
pNIR = NIR reflectance
pRed = red reflectance
pBlue = blue reflectance
C1 = atmosphere resistance red correction coefficient
C2 = atmosphere resistance blue correction coefficient
L = canopy background brightness
G = gain factor

The MODIS sensor on the Terra satellite platform provides us with 16-day composite measures of NDVI/EVI throughout the year.  NASA distributes MODIS data from many of their distributed data centers.
