So, no, data was not erased, it just wasn’t kept in legacy copies, at least that’s why CRU has said and answered to.

Where did they get the temperature reading for the grids? From weather stations, tree rings, individual sources (ex: newspapers) all kinds of sources. But, sometimes one month they would get a reading from one place in the 5 x 5 degree grid, the next month from a location at a totally different place in the 5 x 5 degree grid.

Over the years, they would go back, get NEW, BETTER or AMENDED data, and try to fill in the months and years in each grid the best they could.

But thier current ability to tell you exactly WHERE each of the temperature reading came from, for every month, for every year in every grid, they can’t totally do that. In some cases they can’t even tell if one reading came from one end of the grid and then from the other end of the grid. Geographical locations within the grid and the temperature reading is important.
