  1. Very interesting this temperature and hygrometric distribution in Pittsburgh area, clearly affected by the presence of the 3 rivers. The analysis performed on the MeteoTracker web platform some days ago. (By the way MeteoTracker is a low cost but accurate mini weather station for measurements on the go).
  2. Hallo, sorry for missing your comment. You may know more on the device at this link: https://www.indiegogo.com/projects/meteotracker-weather-station-for-data-on-the-move/reft/25741123/TWF
  3. Hallo cold pools fans! Look at this extreme thermal inversion recorded during a MeteoTracker session in the Fairbanks area (Alaska) on January 26 2021! A difference of as much as 19.2° C (34.5° F) over a distance of approximately 5 km (3.1 miles), with an unbelievable temperature variation from -33.3° C (-27.9° F) to -14.1° C (6.6° F), was detected at around 9 A.M. Alaska time. The analysis performed on the MeteoTracker web platform (vertical profile graph and other tools) shows very well how strong the positive vertical temperature gradient was. (By the way MeteoTracker is a low cost but accurate mini weather station for measurements on the go).
  4. Greetings to all, to be precise it is very difficult to say what the temperature of a city is. This can vary a lot by moving a few hundred meters around the city. An important factor to consider is the urban heat island. The temperature data on the maps below show some examples of HUI in some cities. An urban heat island, or UHI, is a metropolitan area that's a lot warmer than the rural areas surrounding it. Heat is created by energy from all the people, cars, buses, and trains in big cities like New York, Paris, and London. Urban heat islands are created in areas like these: places that have lots of activity and lots of people. There are many reasons for UHIs. When houses, shops, and industrial buildings are constructed close together, it can create a UHI. Building materials are usually very good at insulating, or holding in heat. This insulation makes the areas around buildings warmer. "Waste heat" also contributes to a UHI. People and their tools, such as cars and factories, are always burning off energy, whether they’re jogging, driving, or just living their day-to-day lives. The energy people burn off usually escapes in the form of heat. And if there are a lot of people in one area, that's a lot of heat. Urban areas are densely populated, meaning there are a lot of people in a small space. Urban areas are also densely constructed, meaning buildings are constructed very close together. When there is no more room for an urban area to expand, engineers build upward, creating skyscrapers. All this construction means waste heat—and heat that escapes insulation has nowhere to go. It lingers in and between buildings in the UHI. Nighttime temperatures in UHIs remain high. This is because buildings, sidewalks, and parking lots block heat coming from the ground from rising into the cold night sky. Because the heat is trapped on lower levels, the temperature is warmer. Urban heat islands can have worse air and water quality than their rural neighbors. UHIs often have lower air quality because there are more pollutants (waste products from vehicles, industry, and people) being pumped into the air. These pollutants are blocked from scattering and becoming less toxic by the urban landscape: buildings, roads, sidewalks, and parking lots.
  5. Mild temperatures along the route from Halifax going towards the see at noon time. Data collected with my mini weather station MeteoTracker. It takes also some nice weather pictures.
