Table 5.

Each daily-mean temperature in the Manhattan record from 1895 to 2009 was adjusted on a monthly basis relative to the homogenous monthly-mean temperature data at Manhattan available from USHCN version 2 (Menne et al. 2009). A summary of the adjustments (°C) is presented by decade. These adjustments take into account all nonclimatic biases such as time of observation, station movement, and gradual changes in the environment around the station. The most recent movement of the station occurred on 15 May 1989, and no changes have occurred since that time (Doty 2005).
