University of Michigan Biological Station Weather Observations 1980 – Present

General Information

Data Package:
Local Identifier:	edi.25.1
Title:	University of Michigan Biological Station Weather Observations 1980 – Present
Alternate Identifier:	DOI PLACE HOLDER
Abstract:	This data set includes daily year-round weather measurements and observations recorded at the University of Michigan Biological Station (UMBS) from 1980-present. Data primarily serves the purpose of benefitting UMBS researchers needing access to weather data as a confounding variable. Parameters include maximum and minimum temperatures, precipitation, snowfall, snowpack, and estimated cloud cover and type recorded daily at approximately 08:00. Maximum and minimum temperatures were measured at the Biological Station campus with National Weather Service liquid-in-glass thermometers housed in a Weather Service (a.k.a., Cotton Region) shelter located on State Road. Precipitation was measured with either a Belfort Rainfall Transmitter 5915 or an ETI NOAH IV Total Precipitation Gauge in the “UV Field” located immediately northwest of the Biological Station campus. Snowfall and snowpack were also measured in the UV Field on snowboards using National Weather Service according to National Weather Service snow measurement guidelines. Cloud cover was estimated in oktas and classified into one of the ten basic cloud types.

Definition:

Date on which data collection is occurring.

Time at which data collection began. Time was not recorded prior to 2017-10-01.

Maximum air temperature reached over the previous 24 hours. Measured by National Weather Service liquid-in-glass thermometers at Weather Service shelter to the nearest degree. When specified in flags and notes, temperature records were supplied with data logged by an iButton Thermochron in the Weather Service Shelter or by the UV-B temperature sensor in the UV Field. Temperature values recorded in the UV Field were multiplied by a correction factor (.882 for max temps and .847 for min temps) calculated by BVK in June 2016.

Minimum air temperature reached over the last 24 hours. Measured by National Weather Service liquid-in-glass thermometers at Weather Service shelter to the nearest degree. When specified in flags and notes, temperature records were supplied with data logged by an iButton Thermochron in the Weather Service Shelter or by the UV-B temperature sensor in the UV Field. Temperature values recorded in the UV Field were multiplied by a correction factor (.882 for max temps and .847 for min temps) calculated by BVK in June 2016.

Air temperature at time of observation. Measured by National Weather Service liquid-in-glass thermometers at Weather Service shelter to the nearest degree. When specified in flags and notes, temperature records were supplied with data logged by an iButton Thermochron in the Weather Service Shelter or by the UV-B temperature sensor in the UV Field. Temperature values recorded in the UV Field were multiplied by a correction factor (.882 for max temps and .847 for min temps) calculated by BVK in June 2016.

Precipitation from the previous 24 hours. Measured to the nearest 1/100 inch with a Belfort Rainfall Transmitter 5915 in the UV Field located immediately northwest of the Biological Station campus. Measurements were recorded on charts and transcribed to the nearest hundredth inch.

Precipitation from between 12:00 and 11:59 on this calendar day. Measured to the nearest 1/100 inch with an ETI NOAH IV Total Precipitation Gauge in the UV Field located immediately northwest of the Biological Station campus. Measurements were logged in a Campbell Scientific CR1000 data logger.

Snow from the previous 24 hours. Measured with a ruler to the nearest 1/4 inch until 2019-05-01, and measured to the nearest 1/10 inch from 2019-05-01 until present. Measured in the UV Field located immediately northwest of the Biological Station campus on snowboards using National Weather Service according to National Weather Service snow measurement guidelines.

Accumulated snow depth. Measured with a ruler to the nearest inch. Measured in the UV Field located immediately northwest of the Biological Station campus on snowboards using National Weather Service according to National Weather Service snow measurement guidelines.

Amount of cloud cover as observed from Weather Service shelter. Described in oktas.

Cloud type observed from Weather Service shelter, classified in one of the 10 basic cloud types.

Other notes about weather conditions. Includes extraneous weather and instrumentation changes and damage.

Description:

Maximum and minimum temperatures were measured at the Biological Station campus with National Weather Service liquid-in-glass thermometers housed in a Weather Service (a.k.a., Cotton Region) shelter located on State Road. Measurements were recorded to the nearest degree Fahrenheit. In instances where temperatures were not collected daily from the Cotton Region Shelter, temperature records were supplied with data logged by an iButton Thermochron in the Cotton Region Shelter or by the UV-B temperature sensor in the UV-B field. Temperature values recorded in the UV-B field were multiplied by a correction factor (.882 for max temps and .847 for min temps) calculated by BVK in June 2016. Precipitation was measured with either a Belfort Rainfall Transmitter 5915 or an ETI NOAH IV Total Precipitation Gauge in the “UV Field” located immediately northwest of the Biological Station campus. Measurements from the Belfort were recorded on charts and transcribed to the nearest hundredth inch. Measurements from the ETI were logged in a Campbell Scientific CR1000 data logger. Snowfall and snowpack were also measured in the UV Field on snowboards using National Weather Service according to National Weather Service snow measurement guidelines (https://www.weather.gov/media/coop/Snow_Measurement_Guidelines-2014.pdf).
