atoru I.k Ceilometer (30-second) data are used to derive cloudiness at or below 12,000 feet. This cloudiness is the mean cloud cover detected during sunrise to sunset (SR.SS), or midnight to midnight (MN-MN).
Satellite data are used to derive cloudiness above 12,000 feet. Effective Cloud Amount is based on the cloud cover and the transparency of the clouds within the satellite field or view (approx.
31X31 miles).
Sky Condition is based on the sum (not to exceed
- 8) of the sunrise to sunset cloud cover below and above 12,000 feet. lioth ceilometer and satellite ditto must be present to compute Sky Condition.
Clear = 0-2 oktas, Partly Cloudy = 3.6 oktas, Cloudy = 7.8 oktas.
A Heating (Cooling) Degree Day is the difference between the average daily temperature and 65 degrees F. The H1) season begins July 1, the CDD season begins January 1.
-Dew Point is the temperature to which the air must be cooled to achieve 100% relative humidity. Wet Bulb is the temperature the air would have ir cooled to saturation at constant pressure by evaporation of water into it.
Snow Depth, Snowfall, and Sunshine data may come front nearby. sites that the National Weather Service deems -Climatologically representative or this site,.*

Satellite data are used to derive cloudiness above 12,000 feet. Effective Cloud Amount is based on the cloud cover and the transparency of the clouds within the satellite field of view (approx. 31x31 miles).
Sky Condition is based on the sum (not to exceed
- 8) of the sunrise to sunset cloud cover below and above 12,000 feet. Both ceilometer and satellite data must be present to compute Sky Condition.
Clear = 0=-2oktas, Partly Cloudy = 3-6 oktas, Cloudy = 7-8 oktas.
A Heating (Cooling) Degree Day is the difference between the average daily temperature and 65 degrees F The HDD season begins July 1, the CDD season begins January 1.
Dew Point is the temperature to which the air must be cooled to achieve 100% relative humidity.
Wet Bulb is the temperature the air would have if cooled to saturation at constant pressure by evaporation of water into it.
Snow Depth, Snowfall, and Sunshine data may come from nearby sites that the National Weather Service deems.Cl imatoldgically representative of this site.

REFERENCE NOTES &
SUPPLEMENTAL SUMMARIES
- = Extreme for the month (last occurence if more than one)
T = Trace precipitation amount
+ = also occurs on earlier date FG+ = Heavy fog, visibility.25 miles or less BLANK entries denote missing or unreported data Resultant wind is the vector sum of the wind speeds and directions divided by the number of observations.
Wind direction is recorded in tens of degrees (2 digits) clockwise from true north. '00' = calm,
'VR' = variable.
Precipitation is for the 24-hour period ending at the time indicated in the column heading.
Water Equivalent of snow on the ground is reported only when the depth is 2 or more inches.

'-' = Light WASHINGTON DC, DC SEPTEMBER 2005 Ceilometer (30-second) data are used to derive cloudiness at or below 12,000 feet. This cloudiness is the mean -loud -over detected during sunrise to sunset (SR-SS), or midnight to midnight (MN-MN).
Satellite data are used to derive cloudiness above 12,000 feet. Effective Cloud Amount is based on the cloud cover and the transparency of the clouds within the satellite field of view (approx. 31x31 miles).
Sky Condition is based on the sum (not to exceed
- 8) of the sunrise to sunset cloud cover below and above 12,000 feet. Both ceilometer and satellite data must be present to compute Sky Condition.
Clear = 0-2 oktas, Partly Cloudy = 3-6 oktas, Cloudy = 7-8 oktas.
A Heating (Cooling) Degree Day is the difference between the average daily temperature and 65 degrees F. The HDD season begins July 1, the CDD season begins January 1.
Dew Point is the temperature to which the air must be cooled toachieve 100% relative humidity.
Wet Bulb is the temperature the air would have if cooled to saturation at constant pressure by evaporation of water into it.
Snow Depth, Snowfall, and Sunshine data may come from nearby sites that the National Weather Service deems Climatologically representative of this site.

REFERENCE NOTES &
SUPPLEMENTAL SUMMARIES
- = Extreme for the month (last occurence if more than one)
T = Trace precipitation amount
+ = also occurs on earlier date FG+ = Heavy fog, visibility.25 miles or less BLANK entries denote missing or unreported data Resultant wind is the vector sum of the wind speeds and directions divided by the number of observations.
Wind direction is recorded in tens of degrees (2 digits) clockwise from true north. '00' = calm,
'VR' = variable.
Precipitation is for the 24-hour period ending at the time indicated in the column heading.
Water Equivalent of snow on the ground is reported only when the depth is 2 or more inches.

Light WASHINGTON DC, DC OCTOBER 2005 Ceilometer (30-second) data are used to derive cloudiness.at or below 12,000 feet. This cloudiness is the mean cloud cover detected during sunrise to sunset (SR-SS), or midnight to midnight (MN-MN).
Satellite data are used to derive cloudiness above 12,000 feet. Effective Cloud Amount is based on the cloud cover and the transparency, of the clouds within the satellite field of view (approx. 31x31 miles).
Sky Condition is based on the sum (not to exceed
- 8) of the sunrise to sunset cloud cover below and above 12,000 feet. Both ceilometer and satellite data must be present to compute Sky Condition.
Clear = 0-2 oktas, Partly Cloudy = 3-6 oktas, Cloudy = 7-8 oktas.
A Heating (Cooling) Degree Day is the difference between the average daily temperature and 65 degrees F. The HDD season begins July 1, the CDD season begins January 1.
Dew Point is the temperature to which the air must be cooled to achieve 100% relative humidity.
Wet Bulb is the temperature the air would have if cooled to saturation at constant pressure by evaporation of water into it.
Snow Depth, Snowfall, and Sunshine data may come from nearby sites that the National Weather Service deems Climatologically representative of this site.

REFERENCE NOTES &
SUPPLEMENTAL SUMMARIES
- = Extreme for the month (last occurence if more than one)
T = Trace precipitation amount
+ = also occurs on earlier date FG+ = Heavy fog, visibility.25 miles or less BLANK entries denote missing or unreported data Resultant wind is the vector sum of the wind speeds and directions divided by the number of observations.
Wind direction is recorded in tens of degrees (2 digits) clockwise from true north. '00' = calm,
'VR' = variable.
Precipitation is for the 24-hour period ending at the time indicated in the column heading.
Water Equivalent of snow on the ground is reported only when the depth is 2 or more inches.

Satellite data are used to derive cloudiness above 12,000 feet. Effective Cloud Amount is based on the cloud cover and the transparency of the clouds within the satellite field of view (approx. 31x31 miles).
Sky Condition is based on the sum (not to exceed
- 8) of the sunrise to sunset cloud cover below and above 12,000 feet. Both ceilometer and satellite data must be present to compute Sky Condition.
Clear = 0-2 oktas, Partly Cloudy = 3-6 oktas, Cloudy = 7-8 oktas.
A Heating (Cooling) Degree Day is the difference between the-.average daily temperature and 65 degrees F The HDD season begins July 1, the CDD season begins January 1.
Dew Point is the temperature to which the air must be cooled to achieve 100% relative humidity.
Wet Bulb is the temperature the air would have if cooled to saturation at constant pressure by evaporation of water into it.
Snow Depth, Snowfall, and Sunshine data may come from nearby sites that the National Weather Service deems, Climatologically, representative of this site.

REFERENCE NOTES &
SUPPLEMENTAL SUMMARIES
- = Extreme for the month (last occurence if more than one)
T = Trace precipitation amount
+ = also occurs on earlier date FG+ = Heavy fog, visibility.25 miles or less BLANK entries denote missing or unreported data Resultant wind is the vector sum of the wind speeds and directions divided by the number of observations.
Wind direction is recorded in tens of degrees (2 digits) clockwise from true north. '00' = calm,
'VR' = variable.
Precipitation is for the 24-hour period ending at the time indicated in the column heading.
Water Equivalent of snow on the ground is reported only when the depth is 2 or more inches.

Hoavy
= Moderate Ught WASHINGTON DC, DC DECEMBER 2005 Ceilometer (30-second) data are used to derive cloudiness at or below 12,000 feet. This cloudiness is the mean cloud cover detected during sunrise to sunset (SR-SS), or midnight to midnight (MN-MN).
Satellite data are used to derive cloudiness above 12,000 feet. Effective Cloud Amou nt is based on the cloud cover and the transparency of the clouds within the satellite field oa view (approx. 31x31 miles).
Sky Condition is based on the sum (not to exceed
- 8) of the sunrise to sunset cloud cover below and above 12,000 feet, Both ceilometer and satellite data must be present to compute Sky Condition.
Clear = 0-2 okras, Partly Cloudy = 3-6 oklas, Cloudy = 7-8 oktas.
A Heating (Cooling) Degree Day is the difference between the average daily temperature and 65 degrees F. The HDD season begins July 1, the CDD season begins January 1.
Dew Point is the temperature to which the air must be cooled to achieve 100% relative humidity.
Wet Bulb is the temperature the air would have if cooled to saturation at constant pressure by evaporation of water into it.
Snow Depth, Snowfall, and Sunshine data may come from nearby sites that the National Weather Service deems Climatologically representative of this site.
