Sawmill Area Information

Sawmill Ridge Weather Summaries

Introduction

The location is in the mountains west of Denver, Colorado, in an aspen and conifer forest. The elevation is 9,000 feet (2745 m). The degree-day climate rating for the area was considered 9,300 degree-days (5150 Celsius degree-days). (Compared with a value of some 5280 feet (3300 m) for Denver.) There are occasional windstorms with winds as much as 100 miles per hour (160 kph) in the area.

A person with severe chemical sensitivity (a hypersensitivity to many petrochemical and formaldehyde chemicals) built and moved to a healthy house on the Sawmill Ridge in 2004, and has been recording the local weather ever since.

At that time, the only known prior weather data for this area was a short term Weather Bureau station at the Caribou Ranch, located some 10 miles south of the Sawmill Ridge, with a comparable elevation.

Methodologies -

For temperature data, one or move commercial temperature sensors with a one-tenth degree specified accuracy are mounted in a sheltered area on the north side of the building, insulated from the building heat and shaded from the summer sunshine. The temperature in degrees Fahrenheit is recorded daily, in YYYY/MM/DD scientific format using a 0700 to 0700 mountain time frame the next day. The maximum and minimum values from the previous day are considered the readings for the current day. Note that this methodology is not in accordance with Weather Bureau practice.

The temperature gauge(s) are calibrated annually in a stirred ice/water bath and expected to read 32.0 degrees within a .03 degree.

Explanation of the Average Composite Outdoor Temperatures

This is a composite plot of the average outside temperatures for the years 2006 ... 2017.

The plot consists of the following -

Time is plotted vertically every seven days, using the scientific date format of year/month/day (YYYY/MM/DD).

Temperature is plotted horizontally, in degrees Fahrenheit.

Keys are plotted that represent the average of the temperatures over the previous six days and the current day with a key of 6 for the year 2006 up through G for the year 2017.

For a few detailed examples -

Time is plotted vertically every seven days, using the scientific date format of year/month/day (YYYY/MM/DD). Fill in the question marks with the last two digits of the year as needed.

Temperature is plotted horizontally, in degrees Fahrenheit.

Keys are plotted that represent the maxima of the temperatures over the previous six days and the current day with a key of 6 for the year 2006 up through G for the year 2017.

In the Seven Day Composite Average Temperature Page -

This is a composite plot of the average outside temperatures for the years 2006 ... 2017.

The line 20??/05/06 represents the average of the data values for April 30th through May 06th. The "GAH68E7FC" string represents the temperature values for 2016, 2010, 2017, 2006, 2008, 2014, 2007, 2015, and 2012, starting at a temperature of 38 degrees fahrenheit and ending at a temperature of 50 degrees fahrenheit.

In the Seven Day Composite Maxima Outdoor Temperatures Page -

This is a composite plot of the maximum outside temperatures for the years 2006 ... 2016.

The line 20??/03/11 represents the data values for March 05th through March 11th. The "6 8 FAEH9G" string represents the temperature values for 2015, 2010, 2014, 2017, 2009, and 2013, starting at a temperature of 20 degrees Fahrenheit and ending at a temperature of 45 degrees Fahrenheit.

The Annual Plot section presents the annual temperature maxima for the years 2006 ... 2017. For example, the annual maximum temperature for 2009 was 82.60 degrees Fahrenheit.

Wind Speed Plot

An empirical estimate, based on the Beaufort Scale, is made of whether the day was windy, breezy, or calm - no wind.

Windy amounts to ongoing, sustained winds which would be described by the Beaufort scale of 6 or more, where large branches are moving, overhead wires are whistling, and using an umbrella is problematical. The wind speeds for this rating range from 25 miles an hour or more and are assigned 64 miles/hour for this study.

Breezy amounts to light, but sustained winds with a Beaufort scale ranging from 3 to 6, in which leaves and twigs move, and the wind would extend a flag. The wind speeds for this range are from 8 to 25 miles an hour and are assigned 16 mph for this study.

Calm, is no wind, or negligible sustained air motion. which would be a Beaufort scale of 0 to 2. The wind speeds for this category range from zero to eight miles an hour and are assigned 4 mph for this study.

The wind speed estimates are averaged over 7 days to minimize weather periodicities.
