Record Temperature Readings Throughout Los Angeles Caused By ‘Faulty Weather Stations,’ Meteorologist Says

Daily Caller:

Nearly every record-high temperature reported over the last few days in the Los Angeles area are from weather stations “compromised by heat sources and heat sinks,” according to a veteran meteorologist.

“In my opinion, the data from these stations is worthless,” California-based meteorologist Anthony Watts wrote on his blog Watts Up With That.

That’s not to say Los Angeles wasn’t scorching hot. Temperatures in much of greater Los Angeles were in the triple digits, according to the National Weather Service.

On the contrary, what Watts claims is that artificial heat sources and sinks produce localized heat around weather stations, adding the few degrees necessary to qualify as records. In general, cities are warmer than surrounding countryside owing to the urban heat island effect.

For example, downtown Los Angeles reported a daily record high temperature of 108 degrees Fahrenheit on Friday. Watts, however, noted the weather station was on top of a parking garage surrounded by vehicles. The weather station was relocated to the University of Southern California (USC) campus in 1999 where meteorologists said it would be less prone to extreme swings, but Watts said that station’s had problems in the past.  more here

  3. doesn’t matter what temps are recorded … not until anyone can tell us what the optimized temp should be … anywhere, at any time

  4. I’ve been studying this strange phenomenon and have come to the following conclusion. It starts to warm up in the spring. In the summer, my study shows it gets hotter but begins to cool come fall. Winter it seems to get the coldest. Then a new cycle starts in spring again. Been happening as long as I can remember.
