1951 - Becomes Home to National Weather Records Center
After the war, Grove Arcade continued under federal ownership and eventually became the headquarters of the National Weather Records Center (later known as the National Climatic Data Center). Given its size, Grove Arcade was an ideal location to house millions of pages of weather records.
It was becoming increasingly popular at that time to store data on pieces of paper called “punch cards” which could be read by early computers. Millions of pieces of paper were stored in filing cabinets throughout Grove Arcade. So many, in fact, that it was thought that the combined weight of the cards would cause structural damage to the building!
