A Question Of Scale: Making Meteorological Knowledge And Nation In Imperial Asia, Fiona Williamson, Vladimir Jankovic Nov 2020

A Question Of Scale: Making Meteorological Knowledge And Nation In Imperial Asia, Fiona Williamson, Vladimir Jankovic

Research Collection School of Social Sciences

This special issue of History of Meteorology explores processes of making, communicating, and embedding modern meteorological knowledge in late nineteenth and early twentieth century imperial Asia. Its focus is on the institutionalisation of meteorology in key nation-building activities such as developing agricultural services, synoptic mapping to predict storms, and participation in scientific organisations and initiatives. Collectively, the essays explore the intersection of local, regional, and international scales and processes in generating new forms of state-sponsored meteorological practices and institutions, though complex multi-layered networks involving different actors and modes of information flow across multiple scales. In so doing, they reveal the …


Archives Of Societies And Historical Climatology In East And Southeast Asia, Fiona Williamson, Qing Pei Nov 2020

Archives Of Societies And Historical Climatology In East And Southeast Asia, Fiona Williamson, Qing Pei

Research Collection School of Social Sciences

Major sources of social archives for paleoclimatology in East and Southeast Asia include ancient annals and chronicles, instrumental records from government, military or missionary bodies, and private records such as diaries. Records are rich but scattered and of inconsistent quality, often requiring different forms of cross-validation and homogenization from those in the Western world. This article discusses these source types.


Responding To Extremes: Managing Urban Water Scarcity In The Late Nineteenth-Century Straits Settlements, Fiona Williamson Oct 2020

Responding To Extremes: Managing Urban Water Scarcity In The Late Nineteenth-Century Straits Settlements, Fiona Williamson

Research Collection School of Social Sciences

In 1877, the major towns of the Straits Settlements - Singapore, George Town, Penang Island and Malacca - suffered a drought of exceptional magnitude. The drought’s natural instigator was the El Niño phase of the El Niño Southern Oscillation (ENSO), a climatic phenomenon then not understood by contemporary observers. The 1877 event has been explored in some depth for countries including India, China and Australia. Its impact on Southeast Asia however is less well-known and the story of how the event unfolded in Singapore and Malaysia has not been told. This paper explores how the contemporary British government responded to …


Summer Average Urban-Rural Surface Temperature Differences Do Not Indicate The Need For Urban Heat Reduction, Alberto Martilli, Matthias Roth, Winston T. L. Chow, Et Al Jun 2020

Summer Average Urban-Rural Surface Temperature Differences Do Not Indicate The Need For Urban Heat Reduction, Alberto Martilli, Matthias Roth, Winston T. L. Chow, Et Al

Research Collection School of Social Sciences

This is a comment to the paper "Magnitude of urban heat islands largely explained by climate and population" by Manoli et al. (2019, Nature 573 p. 55-60; https://doi.org/10.1038/s41586-019-1512-9)


Singapore's Climate Action: It Is Time To Be More Ambitious, Winston T. L. Chow Jun 2020

Singapore's Climate Action: It Is Time To Be More Ambitious, Winston T. L. Chow

Research Collection School of Social Sciences

Some nations have declared net-zero carbon emission targets by 2050. Businesses and the people here know Singapore can punch above its weight. The government should lend its support.


The Science Of Stifling Heat: Recognising Urban Climate Change In The Straits Settlements, Fiona Williamson Jun 2020

The Science Of Stifling Heat: Recognising Urban Climate Change In The Straits Settlements, Fiona Williamson

Research Collection School of Social Sciences

Heat is a ubiquitous part of tropical living. During the nineteenth century consumers and writers of travel literature, explorers and colonists became increasingly familiar with the endless, languid summers of tropical climates where continued, unrelenting heat and humidity created a daunting climate for the European.


A Global Regression Method For Thermal Sharpening Of Urban Land Surface Temperatures From Modis And Landsat, James. W. Wang, Winston T. L. Chow, Yi-Chen Wang Apr 2020

A Global Regression Method For Thermal Sharpening Of Urban Land Surface Temperatures From Modis And Landsat, James. W. Wang, Winston T. L. Chow, Yi-Chen Wang

Research Collection School of Social Sciences

Land surface temperatures (LST) in urban landscapes are typically more heterogeneous than can be monitored by the spatial resolution of satellite-based thermal infrared sensors. Thermal sharpening (TS) methods permit the disaggregation of LST based on finer-grained multispectral information, but there is continued debate over which spectral indices are most appropriate for urban TS, and how they should be configured in a predictive regression framework. In this study, we evaluate the stability of various TS kernels with respect to LST at different spatial (Landsat 8) and diurnal (MODIS) scales, and present a new TS method, global regression for urban thermal sharpening …
