H2SO4-H2O,
HNO3-H2O, or ternary HNO3-H2O-H2SO4 solutions (lta_density.pro)

aerosols
(wt.% H2SO4), according to Steele and Hamill, 1981 (sulfate.pro)

sulfate
aerosols (wt.% H2SO4), according to Tabazadeh et al., 1997 (sulfate_tabaz.pro)
- Altitude change between two
pressure levels using the hydrostatic equation (hydrostatic.pro)

Geometry
- Great circle distance and
heading
between two locations (great_circle.pro)
- Relate angular field of view at
the
spacecraft to linear distance subtended at tangent for a limb view (ang2lin_fov.pro)
- Relate linear distance subtended
at
tangent for a limb view, to angular field of view at the spacecraft (lin2ang_fov.pro)
- Calculate path length of the
tangent
point sample volume for a limb view from space (tan_path_len.pro)

Math
- Two-point linear interpolation (interp_2pt.pro)
- Compute a histogram for your
data,
the median value (most frequent), and the mean and std. deviation (histo.pro)
- Find all interpolates on a
multi-valued function (interp_all.pro)
- Generate a set of random numbers that has a mean value below a specified limit (get_random_nums.pro)
- Find the half power points for a curve (e.g., a FOV or RSR curve) (half_power.pro)
- Generate a uniform logarithmic series of numbers (range_logx.pro)
