Highest heat index: In the observation above at Dhahran, Saudi Arabia, the heat index ("feels like" temperature) was 81.1 °C (178.0 °F). [ 201 ] Highest temperature with 100% relative humidity : A temperature of 34 °C (93 °F) with 100% relative humidity in Jask , Iran , on 21 July 2012.
Integrated Surface Database (ISD) is global database compiled by the National Oceanic and Atmospheric Administration (NOAA) and the National Centers for Environmental Information (NCEI) comprising hourly and synoptic surface observations compiled globally from ~35,500 weather stations; it is updated, automatically, hourly.
The initial version of Global Historical Climatology Network was developed in the summer of 1992. [3] This first version, known as Version 1 was a collaboration between research stations and data sets alike to the World Weather Records program and the World Monthly Surface Station Climatology from the National Center for Atmospheric Research.

As a two-part measurement, heat index can be measured using charts or online calculators to explore the difference between the two figures and the amount of danger that heat index represents. A ...
Typical meteorological year (TMY) is a collation of selected weather data for a specific location, listing hourly values of solar radiation and meteorological elements for a one-year period. The values are generated from a data bank much longer than a year in duration, at least 12 years.
Work Relief in an Increased Heat Index: 4 Key Takeaways. The human body, outside of light to regular physical activity, is not meant to overly exert itself in this kind of high humidity.
Other techniques which have been used include examining records of the time of crop harvests, the treeline in various locations, and other historical records to make inferences about the temperature. These proxy reconstructions are indirect inferences of temperature and thus tend to have greater uncertainty than instrumental data.
A generalized view of the heat index showing how the perception of heat by the human body increases with temperature but more rapidly at higher humidity levels. The heat index of a given combination of temperature and humidity is defined as the dry-bulb temperature which would feel the same if the water vapor pressure were 1.6 kPa. Quoting ...
