.. py:function:: stp_convert_dry(x, t, p1)

   Convert a measurement to STP conditions for dry air.

   This function adjusts a measurement from actual conditions to standard
   temperature and pressure (STP) conditions for dry air. It follows the
   approach of `stp.convert.dry` by Roman Pohorsky.

   :param x: Measured value to be converted.
   :type x: float or array-like
   :param t: Temperature in °C.
   :type t: float or array-like
   :param p1: Pressure in hPa.
   :type p1: float or array-like

   :returns: Measurement converted to STP conditions.
   :rtype: float or array-like

   .. rubric:: Notes

   The conversion process involves:
     1. Converting the pressure from hPa to Pa.
     2. Converting the temperature from °C to Kelvin.
     3. Calculating the STP conversion factor and applying it to measurement.

   ...     df_level0['FC_CO2'],
   ...     df_level0['T ref'],
   ...     df_level0['FC_P corr']
