NEA AND SLA SIGN MOU TO SHARE GLOBAL NAVIGATION SATELLITE SYSTEM (GNSS)-DERIVED MOISTURE DATA FOR WEATHER MONITORING APPLICATION

Singapore, 2 August 2022 – The National Environment Agency (NEA) and the Singapore Land Authority (SLA) have signed a Memorandum of Understanding (MOU) to develop the use of Global Navigation Satellite System (GNSS) data obtained from SLA’s Singapore Satellite Reference Network (SiReNT) to enable NEA to better monitor island-wide atmospheric moisture. The five-year collaboration is aimed at benefitting Singapore with additional data for weather monitoring, as well as facilitating exploratory studies for weather forecasting.

  1. 2 Meteorological observations are vital for forecasting the weather, monitoring the climate, and producing timely warnings of hazardous weather events. Meteorological Service Singapore (MSS) routinely collects a range of observational data such as temperature, wind, and moisture from ground-based and airborne sensors. At MSS’ Upper Air Observatory (UAO), sensors attached to a weather balloon are routinely released twice a day to obtain measurements of these weather elements at different heights of the atmosphere. In 2019, MSS installed a GNSS reference station at UAO to derive continuous estimates of moisture in a column of the atmosphere1, known as the integrated precipitable water vapour, to supplement the sounding data obtained from the weather balloon.

  2. 3 Under the MOU, MSS’s GNSS station will be integrated into SiReNT, and enable MSS to obtain islandwide, continuous and near real-time atmospheric moisture readings. This non-conventional moisture data will augment MSS’s existing observation network data, providing higher resolution and more frequent observation data, which allows for investigative studies into potential applications for weather forecasting (refer to Annex A for an infographic of the GNSS moisture data collection process).

  3. 4 The collaboration will also expand SLA’s SiReNT station network, which currently comprises nine reference stations spread across Singapore. With the addition of NEA’s GNSS base receiver station at UAO that will be incorporated into SiReNT, together with two upcoming additional coastal SiReNT reference stations2, the network will be expanded to 12 stations with additional receivable data. The SiReNT system can correct positional errors in GNSS signals and produce precise positioning data of up to 3 cm in accuracy. The SiReNT technology supports innovation in diverse industries such as autonomous vehicles, construction automation and logistics, and monitoring of land height and sea-level changes in Singapore. The expansion of stations by the end of 2022 will further improve stability to

services and applications in various key industries currently supported by SiReNT. It can also be further leveraged for novel uses in climate-related scientific studies (refer to Annex B for a background of SLA’s SiReNT station network).

  1. 5 Mr Luke Goh, CEO of NEA, said, “The collaboration between NEA and SLA highlights our commitment to achieve synergies and tap on enablers across the public sector. This partnership provides a platform for NEA to utilise SLA’s expertise in GNSS data collection and processing, enabling NEA to explore non-traditional methods to enhance our weather monitoring and forecasting capabilities.”

  2. 6 Mr Colin Low, CEO of SLA said, “This collaboration with NEA is part of SLA’s continuous effort to work with parties from both private and public sector to unlock diverse uses for SiReNT and SLA’s many geospatial products. We believe that by pooling expertise from various parties we can spark more innovation and uncover practicable solutions that can benefit Singapore and our industries. We are excited to work with NEA to study the novel use of SiReNT data for enhanced weather monitoring and investigative studies in weather forecasting and climate change. The many experiences shared and gained from this collaboration will be a building block for future innovations in this field.”

About the Singapore Land Authority

Singapore Land Authority (SLA) is a statutory board with the Ministry of Law. Its mission is to optimise land resources for the social and economic development of Singapore. SLA manages some 11,000 hectares of State land and about 2,700 State properties, which have largely been tenanted out for a variety of uses. It also manages land sales, leases, acquisitions and allocation, developing and marketing land-related information, and maintaining the national land information database through digitised land information services. Being the national land registration authority for property transactions, SLA issues and guarantees land titles in Singapore. It also manages and maintains the national land survey system, where boundaries or legal limits of properties are defined, based on a coordinated cadastre survey system. The use of geospatial information is also spearheaded by SLA through a national collaborative environment where geospatial data, policies and technologies are established and defined, thereby fostering innovation, knowledge and value creation for the Government, enterprises and community.

Background of the Satellite Reference Network (SiReNT)

Developed by the Singapore Land Authority (SLA) in 2006, the Singapore Satellite Positioning Reference Network (SiReNT) is a national reference network infrastructure that supports real-time high precision positioning, navigation, and monitoring of up to 3cm. The technology is used by Government agencies and private companies in applications where precise positioning is required. This includes the development and operation of self-mobility platforms, construction automation and high accuracy mapping.
