NYT Says We’re Too Dumb To Understand Climate Change

By Robert Tracinski I recently wrote about the wretched reporting on the claim that 2016 was the “hottest year on record,” using as my main example a New York Times article by Justin Gillis that gave his readers none of the relevant numbers they could use to evaluate that claim. None of them. If you…

Yes, where are the error bars?!

First Day of Pyranometer Operation

In a previous post, I talked about installing a new pyranometer to my weather station. Below is a graph of today’s solar radiation flux in W/m^2.

The graph clearly shows when the instrument was in shade (7:30 – 9:30 AM EST). Maximum value was after noon due to the fact that the longitude is about 3 deg west of the 75th meridian and because the equation of time for today is 3 minutes. The maximum solar elevation angle was about 28 deg. The optical depth of the atmosphere is significantly higher at such a low angle than if the sun was at zenith.

Pyranometer

Today, I installed a new weather instrument, for 2017 and beyond, to my personal weather station (PWS). I installed a pyranometer to measure the solar radiation flux density (W/m**2). The data from the instrument will be sampled every 30 minutes, along with the other parameters that are already being logged.

I have been told that the State College region is cloudier than most. Now I can measure just how “gray” the environment is here.

Indian Summer

Some would say that our area is now in the midst of Indian Summer (is that politically correct?). Yesterday morning, the temperature in Stormstown fell just below 32 deg F (31.6 F at 6:00 AM EDT), the first recorded freezing temperature of the season. There was frost on the lawns as seen below:

p1020884

As the sun rose, the frost that was in full sunlight dissipated, while the frost in shadow remained.

The foliage has some color. However, it is not expected to be spectacular this year as the region has suffered a drought over the summer.

p1020879

It is definitely jacket weather here, nonetheless.

Tropical Storm Matthew

Tropical Storm Matthew formed today. It is forecast to become a hurricane this Friday.

What is unusual is that the forecast track has the system making a hard right turn to the north sometime this weekend. Most of the models are in agreement to that forecast.

However, the two main models, GFS and ECMWF, disagree on where it will track a week from now. An earlier run of the GFS had it going up Chesapeake Bay next Thursday. The ECMWF has it moving slower with a possible landfall in southern Florida, so this should be watched carefully in the coming days.
