It is so hot this week that my thoughts naturally turn to the weather. A
recent article in CIO Magazine titled How
to Profit From the Ultimate Big Data Source: The Weather inspired me to
talk with former media industry research executive Rob Frydlewicz about analyzing
weather using Big Data. Rob publishes
the NYC Weather Archive blog and for years has been
examining large data sets for strategic insights and forecasting purposes.
In
talking to Rob about how he mines this data and divines his insights, I
realized that the true value of a strategic researcher is their ability to
discern instructive patterns from seemingly disparate numbers and make accurate
valuable predictions from them. It is arguably one of the most important
talents needed in today’s business world.
CW: As a
media researcher, you have always been surrounded by lots of data. What makes
today’s data different from years ago?
RF:
A generation ago, a stack of computer printouts dumped on your desk was
referred to, usually disparagingly, as a “data dump.” Since then these “dumps” have grown
exponentially and are now handled with reverence and referred to glowingly as
Big Data. They are all around us, with
most attention going to respondent-level TV viewing data, Wall Street’s
second-by-second transfer of millions of dollars and shares, and the granular
telephone and online usage patterns being turned over to the NSA.
CW: Rob,
tell me about your use of weather data for your blog. How did you get started
in it?
RF:
As a media research professional I’ve had plenty of experience being immersed
in media usage, advertising spending and Census data, to name just a few. And recently I added weather data to my
repertoire. In my weather blog, NYC
Weather Archive, I tell stories about interesting atmospheric conditions that have occurred in New York.
The building blocks for these analyses are the detailed, daily weather
information collected by the National Weather Service. When I began the blog, its scope was limited
to the data I subscribed to. Then, last
year, all of its weather data, for as long as it’s been collected, was made
available free of charge. This greatly
enlarged the possibilities for further interesting analyses.
CW: With so
much raw data, how are you able to make sense of it? How do you even start to
analyze it?
RF:
It’s only by wading through the data that many of my posts have taken
shape. Very often, as I pore over the
statistics with a particular story in mind, other patterns form before my eyes
and I find myself with other stories to investigate. But unlike so much other person-based Big
Data, no one’s privacy is compromised by looking through all of this weather
data!
CW: What is
your advice to companies seeking an expert in Big Data analytics?
RF:
Big Data is only as powerful as the persons who sift through it - analysts who
thoroughly enjoy probing the data, discerning patterns and shaping fascinating
and useful stories.
CW: Can you
offer a list of blog posts that have used Big Data and have resulted in
interesting insights?
RF:
Yes. Some of my favorites include – March Madness – 80-Degree Weather in March;
When the Rain is Unrelenting; Biggest & Smallest Temperature Swings; Cold
Weather, no Snow – A Snowlover’s Nightmare; How Common Are “Average”
Temperatures?”; Too Cold to Snow? NYC’s Biggest Snowfalls During Frigid Weather;
Unbearably Warm Summer Nights.
