• "Even Paltridge et al. 2009, which relied on the NCEP reanalysis data, recognized that “[i]t is accepted that radiosonde-derived humidity data must be treated with great caution, particularly at altitudes above the 500 hPa [hectopascal] pressure level.”"
• "Relative humidity ranged between a minimum of 33% and a maximum of 79.8%, while atmospheric pressure hovered around 1009.5 hectopascal."
• "One hundred Pascals (one hectopascal) is equal to 1 millibar of pressure, so that one atmosphere of pressure (14.7 pounds per square inch) is 1013 hectopascals or millibars of pressure."
