Notes:  
1) By convention, downward net fluxes of radiation or other quantities are assigned negative values; upward net fluxes of radiation or other quantities are assigned positive values.  
2) Unidirectional flux values, where the direction of flow is indicated in the name of the parameter (e.g., 204, 205, 211, 212), shall all have positive values irrespective of the direction of flow. Net (vertical) fluxes shall be calculated by subtracting the downward flux values from the upward flux values.  
3) The u and v components of vector quantities are defined with reference to GDS Octet 17 and Table 7. However, if the GDS is not included in a message, then any wind components are assumed to be resolved relative to the grid specified in the PDS with u and v defined as positive in the direction of increasing x and y (or i and j) coordinates respectively.  
4) Provision is made for three types of spectra:  


5) Parameters 81 and 91 show the units as "fraction", thus allowing for a range of coverage. It is up to the user to employ the D (power of ten) scaling to assure that the necessary precision is retained in the numeric values.  
6) Precipitation index (#218) defined as the fraction of
satellite observed pixels with temperatures <235K over 1.0x1.0 box, centered
at the gridpoint. 

7) Flight category values  1 =
Terrestrial Obs; 2 = LIFR; 3 = IFR; 4 = MVFR; 5 = VFR 

8) Confidence indicator values 
0 = Low; 1 = Medium; 2 = High
