How to read and interpret the "DAILY" and "ORBITAL" Average Plots, for the following instruments:

NOAA 15 AVHRR, HIRS, AMSU-A, AMSU-B

Two types of plots are generated for each active satellite, showing (1,2,4,6,8,12,16 possible) 12 plots per page. Clicking the pointer on any graph will expand it to full screen resolution.

I. Long term trending, shows one average point "per Day", for the last 61 days of a given instrument parameter. Each plot point represents an average of 14orbits / 24hours.

II. Short term trending, shows one average point "per Orbit" for the last 61 orbits of a given instrument parameter. Each plot point represents the result of the in orbit values (Average or Sum, Min, Max) for that orbit.
Using the Control T (Ctl+T) function to display a list of the Orbits Data Set Names seen in graph. X-axis positions, Y-axis value of the plot, Full 44 character Data Set Name', time of orbit length in minutes, for each orbit displayed.

Labels
At the very top of the screen is shown the file name(type of plot {Trend15.Day} satellite number{12..} Plots(number currently view) of total number of plots in selection. The Run Day (:135) Julian day Job was processed on the CEMSCS computer.

Across the Bottom of each graph is shown (1) the Name of the Satellite {NOAA 15..}, (2) the Type of plot {Orbit or Day average}, (3) the Year, the start and end Julian Day of the most recent orbits { 2000 JD 030-035} .

Across the Top of each graph is shown (1) a # parameter number, (2) instrument {GAC, HIRS, AMSU A, AMSU B}, (3) plot parameter label description.
Y axis, shows the Minimum and Maximum values divided into Six even segments.
X axis, shows the 61 plotted points, 0 being the most recent.

Plot Values for the Y axis

The NOAA CEMSCS computer produces the trending updates every morning by 7:00 am.
