longitude derivations

  1. longitude from polygon

    See latitude from polygon


  2. longitude from range

    symbol

    description

    unit

    variable name

    \(\lambda\)

    longitude

    \(degE\)

    longitude {:}

    \(\lambda^{B}(l)\)

    longitude boundaries (\(l \in \{1,2\}\))

    \(degE\)

    longitude_bounds {:,2}

    The pattern : for the dimensions can represent {longitude}, or {time,longitude}.

    \[\lambda = \frac{\lambda^{B}(2) + \lambda^{B}(1)}{2}\]
  3. longitude from vertical profile longitudes

    symbol

    description

    unit

    variable name

    \(\lambda\)

    single longitude for the full profile

    \(degE\)

    longitude {:}

    \(\lambda(i)\)

    longitude for each profile point

    \(degE\)

    longitude {:,vertical}

    \(N\)

    number of profile points

    The pattern : for the dimensions can represent {time}, or no dimensions at all.

    \begin{eqnarray} N & = & max(i, \lambda(i) \neq NaN) \\ \lambda & = & \lambda(N/2) \end{eqnarray}
  4. longitude from sensor longitude

    symbol

    description

    unit

    variable name

    \(\lambda\)

    longitude

    \(degE\)

    longitude {:}

    \(\lambda_{instr}\)

    longitude of the sensor

    \(degE\)

    sensor_longitude {:}

    The pattern : for the dimensions can represent {time}, or no dimensions at all.

    \[\lambda = \lambda_{instr}\]
