Summary
By upgrading to the SatLink3 logger/transmitter, the NOC is enhancing the resilience of the South Atlantic Tide Gauge Network. Jeff Pugh from the Marine Physics and Ocean Climate Group at the NOC, says: “The data from this network informs models that assist with projections relating to climate change, and others which provide advance warnings that can help protect life and property. Given the remote locations of the monitoring sites, it is vitally important, therefore, that the instruments are extremely reliable, operating on low power, with very little requirement for service or spares. By transmitting almost live data via satellite, these monitoring systems enable the models to deliver timely warnings; advance notice of tsunami, for example, can be of critical importance.”
WEATHERMONITORING 63 Satellite telemetry is becoming increasingly popular in many other
parts of the world. “Some government and non-commercial organisations are able to utilise a variety of satellites free of charge,” explains OTT’s Nigel Grimsley. “However, the cost of transmitting data via satellite has reduced considerably recently, and now rivals the cost of cellular communications.”
The OTT Hydromet Group manufactures products that enable water professionals to monitor the planet’s most precious resource. Through the delivery of accurate reliable data, OTT’s instruments and services provide essential tools to help protect the environment.
From precipitation through surface and ground water to marine monitoring applications, OTT’s measurement and communication technologies provide a complete picture of the water cycle. OTT and Hydrolab have been longstanding members of the OTT Hydromet Group. Adcon Telemetry was acquired in 2011; Sutron and Lufft joined the group in 2015, and Kipp & Zonen joined in 2017, which means that the company is able to offer the best sensors and data handling technology for every application.
SatLink3 satellite transmitter logger
analogue channels, one 4-20 mA channel and 2 digital inputs. The Vernadsky station includes a barometric pressure sensor, a radar level sensor installed over a heated/insulated stilling well (keeps the inner core free of ice) and two OTT PLS pressure level sensors which provide accurate measurements of water depth.
The network is using the Geostationary Operational Environmental Satellite (GOES) to transmit data. GOES is operated by the United States’ National Oceanic and Atmospheric Administration (NOAA)’s National Environmental Satellite, Data, and Information Service. One minute averaged data is transmitted every 15 minutes. The data is then made freely available on the IOC Sea Level Station Monitoring Facility web site
www.ioc-sealevelmonitoring.org/list.php.
Completely focused on hydro-meteorology and water quality, OTT products have been market leaders for over 140 years and coupled with modern communications technology provide remote access to continuous monitoring data. Further information is also available at www.

Street level map for areas at risk from extreme weather conditions launched
The UK’s first street level map of areas potentially at risk from extreme weather conditions has been warmly received since its launch last month. Created by earth observation company 4 Earth Intelligence (4EI), with support from the Ordnance Survey through its Covid-19 Response licencing, the free at point of use Heat Hazard Postcode data is already being used to plan the provision of urban green spaces, assess vulnerable populations and inform climate change strategy. Early adopters of the data include the Greater London Authority (GLA), numerous local authorities and several central government departments.
“We recognize the danger extreme temperatures pose and the beneficial role Space Data can play. This is particularly pertinent as we continue to face COVID-19 - undoubtedly the most significant public health challenge in generations,” commented Kristina Guida, Manager at the London Climate Change Partnership, part of the GLA. “The 4EI heat hazard postcode data will help us ensure that we can understand where the hazard lies and will support the mitigation planning for reducing the impact on our most vulnerable populations”
Increased day time temperatures, reduced night time cooling, and higher air pollution levels associated with urban areas can significantly impact human health. Contributing to general discomfort, respiratory difficulties, heat cramps and exhaustion the combination of
temperature and pollution can also cause non-fatal heat stroke as well as heat related mortality. It is estimated that the heatwaves of 2019 led to almost 900 additional deaths in England and, with potentially vulnerable households still maintaining self-isolation, it is possible the figures for this year could be higher.
Derived from satellite imagery and created using automated algorithms, the 4EI data identifies hot spots, usually within urban areas, where temperatures can be up to 3-4 degrees higher forming what is known as an Urban Heat Island (UHI). An UHI is a metropolitan area that is warmer than its vicinity. Heat created by energy from people, cars, transport and building’s heating, cooling and ventilation systems, interacts with construction materials to elevate temperatures.
The 4EI Heat Hazard data is being supplied free at the point of use to national organisations and multi-agency partnerships, such as Local Resilience Forums, that are currently involved in the coronavirus response until September 2020. Supplied as a CSV file for use in spreadsheets, the Heat Hazard data includes five categories, demonstrating the tendency of different locations to reach higher temperatures.
