Use an object to represent lookup results: Atmospheric::Result

[ronaldtse]

The ideal approach should be like this.

Each "row" is a separate Atmospheric::Result object. You can use geometric altitude or geopotential altitude (with unit) to build the object.

The different tables will obtain their data from this object. Then we don't have to work with Hashes anymore.

class Atmospheric
  def self.values_at(parameter_name, unit, value)
    Atmospheric::Result.new(
      # ... geopotential_altitude ... unit ...
      # ... geometric_altitude ... unit ...
    )
  end
end

class Atmospheric::Result < Lutaml::Model::Serialization
  attribute :geopotential_altitude, :decimal
  attribute :geopotential_altitude_unit, :string
  attribute :geometric_altitude, :decimal
  attribute :geometric_altitude_unit, :string
  attribute :temperature, :float
  attribute :temperature_unit, :string
  attribute :ppn, :float
  attribute :ppn_unit, :string
  attribute :speed_of_sound, :float
  attribute :speed_of_sound_unit, :string
  # ... other result attributes
end
