The StormTrack Mountsorrel & Rothley Weather Station

From 2007 the Mountsorrel Weather station data was collected via a Davis Vantage ProV1 which has provided a very good service. During the Spring of 2019, The Davis weather station equipment with a new (backup) Davis Vantage ProV2 weather station and added new and more accurate weather sensors from companies such as Gill instruments, Vector Instruments, Campbell Scientific and RM Young in ordeer to provide more accurate weather readings to the village of Montorrel. Data from the sernsors is collected every second and is captured into a SQL database which is located on a desktop computer that is located in my home office. This same computer also host the website that you are viewing this site on now. Conenction to ths website and datbase server is via a residential broadband line supplied by BT Internet.

Main  Weather Station Temperature and Humidity array

The main Temperature and humidity sensor array for the weather station. In the background is the newly replaced Davis Vantage Pro2 all in one weather station with the black rain tipping bucket. The temperature and humidity array consists of 4 calibrated platinum resistance thermometers (PRT) temperature sensors and two humidity sensors. The PRT’s are rated at 1/3 DIN and a reference 1/10 DIN PRT, suppled and calibrated (April 2019) by Sterling Sensors to an accuracy of 0.07°C at 25°C. The humidity sensors (eBay) are outside calibration (October 2015), but claim an accuracy of ±0.8 %RH at 80 %RH at 23°C. The temperature and humidity sensor are housed in METSPEC RAD10 radiation shields to shield the effects of solar heating. The Davis radiation shield is aspirated with a fan which turns on if the solar radiation reported is > 200 W/s and the wind speed is less than 4mph.
** The METSPEC radiation shields “seem” to over record temperatures in very bright sunshine – I am looking to ether fan aspirate the RAD10 radations shilds  or relocate them into an aspirated Stevenson’s shield.
Roof Mounted Anemometer array

The roof mounted wind direction and speed array. According to WMO guidelines, wind meassuring sensors should be mounted at 10 meters high, which they are. However, wind turbulence from the roof lessens the accuracy when the wind is coming from the West or South. There are 4 wind sensors. The black one is for Davis VP2 weather station (ProData). The large “wind vane” is an RMYoung R5103 wind direction and speed which I used to take with me to measure wind speeds in hurricanes. The least side sensor is a modern ultra-sonic anemometer my by Gill Instruments (eBay). It has no moving parts so will never wear out! The near silver cup anemometer is a first-class calibrated (Sep-2016) anemometer by Vector Instruments (eBay) – I was really surprised to find such a highly accurate sensor to cheap! For wind speed and gusts, I take readings from the three sensors (not Davis) every second and then average them out over three seconds to provide current wind speed. I then take a rolling 1 minute, 2 minute and 10-minute max wind speed to provide wind gusts data. Wind direction is averaged over 1 minute from the Ultrasonic and RM Young sensors.
0.1mm tipping Rain Gauge

Rainfall is measured by a 0.1mm resolution SBS1000 WMO first class calibrated (April-2019) tipping bucket rain gauge supplied by EML Ltd. As raindrops fall into the xxx wide funnel collector, they pass through and fall onto a small tipping bucket. When this bucket is full its tips, thus recording that 0.1mm of rain has fallen. By measuring the time taken between tips (and some clever maths) the rain rate is calculated in mm/hour. The Davis VP2 rain collector is a 0.2mm device and it seems to under record rainfall by about 15%
Ground Concrete Temprature probe

Measuring concreate surface temperature is an important consideration when calculating ground frosts and predicting black ice. I use a TP107 BetaTherm 100K6A1IA Thermistor supplied by Campbell Scientific (Shepshed) which as a temperature measuring range of -35° to +50°C and a survival range of -50°C to +100°C which is important as in the summer, on a very hot day Solar radiation can heat the concreate slab to over 60°C. Often the concreate temperature can be below 0°C while the airtime is above freezing. This may then allows black ice to form on untreated roads.
Grass Temeprature Sensor

I use a TP107 BetaTherm 100K6A1IA Thermistor supplied by Campbell Scientific to measure Grass Temperature. Also shown is a grass minimum sensor for the Davis VP2 weather station. The Grass Minimum Temperature is the temperature recorded in open air ground on short turf, with the tip of the thermometer just in contact with the tips of the blades of grass. It is also described as the temperature at 5cm (2in) above ground. The grass minimum temperature often varies substantially from air temperature, which is measured at 2-meters above ground. Often the 2-meter air temperature can be +4°C, while the grass temperature can be below zero at -1 °C

Outlook for Friday to Sunday: Frosty start Friday then turning increasingly wet and windy, with rain clearing Saturday morning. Then very windy Saturday and Sunday with coastal gales and showers, perhaps wintry over hills.
UK Outlook for Sunday 1 Mar 2020 to Tuesday 10 Mar 2020: It will be unsettled with further spells of wind and rain, interspersed with brighter, showery interludes. Wintry showers are possible further north, mainly over hills, but they could fall to lower levels. There will be an ongoing risk of gales, and should deep low pressure systems form, severe gales to storm force winds are possible. Continuing through the period, further wet and windy weather is likely, especially in the north, before more settled conditions start to develop from the south at the end of this period. Temperatures are likely to frequently oscillate between rather cold and rather mild. During any colder interludes, there is likely to be some snow on the high ground of the north.

Mountsorrel is a village in Leicestershire on the River Soar, just south of Loughborough with a population of 6,662 inhabitants. A castle was built in 1080 by Hugh Lupus, but there is evidence of an earlier Norman settlement in the area in the form of pottery fragments. A Roman villa is supposed to have existed on Broad Hill during the 4th century AD, the site of today's quarry, as quarrying during the late 1800s revealed many artefacts including a preserved wooden bucket. However, the first recording of the village was in 1377, when it had a population of 156.

The Mountsorrel Weather Station is located in Mountsorrel which is just South of Loughborough andjust North of Leicester, Leicestershire.
