Multiple choice

In order to read the ESRT tables for relative humidity and dew point, you need the following:

  1. dry bulb and wet bulb temperatures

  2. wet bulb temperature and difference in dry and wet bulb

  3. dry bulb temperature and difference in dry and wet bulb

  4. pressure and temperature
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

In the Earth Science Reference Tables (ESRT), the relative humidity and dew point charts are structured as grids. To find a value, you locate the dry-bulb temperature along the vertical axis and the difference between the dry-bulb and wet-bulb temperatures along the horizontal axis. This intersection gives you the correct reading.
