CAMEX-4 MIPS Surface Station 2 Table of Contents
The University of Alabama in Huntsville (UAH) Mobile Integrated Profiling System (MIPS) includes a 915 MHz Doppler profiler, lidar ceilometer, 12 channel microwave profiling radiometer, Doppler Sodar, Radio Acoustic Sounding System (RASS), Field Mills, and surface observing stations. This dataset consists of data from Surface Station Two containing multiple instruments including an anemometer, rain gauge, thermometer, pyranometer and barometer. Information,collected at 1Hz, includes windspeed and direction as well as precipitation, temperature/humidity, solar radiation, and atmospheric pressure. Surface Station Two data is collected from instrumentation located on the top of a 10 meter tower. The RM Young model 05103 wind monitor measures horizontal wind speeds and direction. It is made of light weight UV stabilized plastic, is very rugged, is resistant to corrosion. Windpseed is measured in the range of 0 to 60 m/s (0-130mph), and can survive gust to 100 m/s (220mph). The Vaisala HMP-45C temperature/humidity probe contains a Platinum Resistance Temperature detector, and a Vaisala Humicap 180 capacitive relative humidity sensor. The instrument is enclosed in a shield with a fan that pulls air through to keep the sensor dry in rainy conditions. The operating temperature is -40C - +60C. The Vaisala PTB210 Digital Barometer is a robust instrument that works well in highly variable temperature conditions. It is constructed of light weight materials, and is corrosion resistant. The instrument will measure pressures from 500 to 1300 hPa, with an accuracy of +- .30 hPA at 20 C, and makes use of a static pressure head to minimize the errors caused by variations in wind speed and direction. The operating temperature range is from -40 to +60 C. The Eppley PSP (or simply Eppley Pyranometer) is an instrument for the measurement of radiation in the range approximately between 285 and 2800 nm. This wavelength range is commonly referred to as shortwave radiation, and it’s primary source is the sun. The RG-600 tipping bucket rain gauge measures rainfall rates up to 2 inches per hour with and accuracy of (+/- ) 1%. A tip occurs with each .01 inch of rainfall. Data is collected approximately every second, and is stored in tabular form (an example of which is shown below). Data includes date/time of observation, pressure, temperature, relative humidity, mean wind direction and speed, standard deviation of wind direction, rainfall and insolation. The first line of the data below defines each column value. Data is in a comma delimited data file. A data file is created for each daily (mission) and is of the form:
where c4gmipss2 represents CAMEX4 ground station MIP surface station #2, 2001.ddd is the four digit year and day of year followed by sfc2 for surface station #1. These data may be imported into a spreadsheet, and an example of such an extraction is shown below. NOTE: The column headers are not included with the data, and are included here for your edification.
