Recording apparatus and determination method

A recording apparatus, comprising:

• a recording head including a plurality of ejection ports and a recording element provided at a position corresponding to each of the ejection ports and configured to generate heat energy, the recording head being configured to eject ink from the ejection ports by driving of the recording element;
• a driving unit configured to apply a driving pulse to drive the recording element;
• a temperature detection unit configured to detect a temperature change in a vicinity of the recording element when the recording element is driven by application of a driving pulse by the driving unit to eject ink;
• a determination unit configured to determine an ink ejection state of each of the ejection ports on a basis of the temperature change detected by the temperature detection unit;
• an acquisition unit configured to acquire information about atmospheric pressure around the recording head;
• and
• a setting unit configured to, when the determination unit determines the ink ejection state, set the driving pulse to be applied by the driving unit to the recording element on a basis of the information about the atmospheric pressure acquired by the acquisition unit.
