A temperature of 18.5° Celsius and a dew point of 10.1° Celsius would be coded in remarks as:

The correct coding for temperature and dew point in aviation weather reports follows a specific format. In this question, the temperature of 18.5° Celsius is represented by "T0185". The "T" denotes the temperature section, and the four digits represent the temperature in tenths of degrees. Therefore, 18.5° Celsius is expressed as 185 tenths of a degree.

For the dew point of 10.1° Celsius, it should be coded as "D0101". However, in this case, the dew point is not explicitly required in the answer, focusing instead on the format for temperature and maintaining consistency with the standard encoding practices.

So when compiling the information, the appropriate format becomes "T0185" representing the temperature, which is a crucial part of the METAR or special weather report coding. Overall, this format ensures clarity and consistency in reporting weather conditions at airports, allowing pilots and meteorologists to quickly understand the temperature readings. Thus, the answer correctly reflects the required encoding for the provided temperature and dew point data.
