Wikipedia's International Geophysical Year begins:
The International Geophysical Year (IGY; French: Année géophysique internationale) was an international scientific project that lasted from 1 July 1957 to 31 December 1958. It marked the end of a long period during the Cold War when scientific interchange between East and West had been seriously interrupted. Sixty-seven countries participated in IGY projects, although one notable exception was the mainland People's Republic of China, which was protesting against the participation of the Republic of China (Taiwan). East and West agreed to nominate the Belgian Marcel Nicolet as secretary general of the associated international organization.
Question: How did Taiwan actually participate? Was there any scientific contribution or were any geodetic measurements performed (inside or outside of Taiwan)? Or was their participation mostly "cosmetic" (for lack of a better word)?
There is some discussion of the IGY and links to other related SE questions in Is Earth's “pear shape” mostly J₃? and in links therein.
