- HadMAT

Marine air temperature anomalies relative to 1961-1990: HadMAT (Rayner et al. 2003, orange) Rayner NA, Parker DE, Horton EB, Folland CK, Alexander LV, Rowell DP, Kent EC, Kaplan A. 2003. Global analyses of sea surface temperature, sea-ice and night marine air temperature since the late nineteenth century. J. Geophys. Res. (Atmospheres) 108(D14): 4407-, DOI:10.1029/2002JD002670 http://hadobs.metoffice.com/mohmat/
- Ishii et al. (uninterpolated)

Marine air temperature anomalies relative to 1961-1990: Ishii et al. (2005, uninterpolated blue). Ishii, M., A. Shouji, S. Sugimoto, T. Matsumoto 2005: Objective analysis of SST and marine meteorological variables for the 20th Century using ICOADS and the Kobe Collection. Int. J. Climatol., 25, 865879. http://ghrsst.nodc.noaa.gov/intercomp.html Data from Masayoshi Ishii, Meteorological Research Institute, Japan Meteorological Agency. Note: This series is not shown before 1900 because it is not corrected for known biases that affect marine air temperature prior to that date.

- Berry and Kent

Marine air temperature anomalies relative to 1961-1990: Berry and Kent (2009, green original climatology period is different so adjusted to average anomaly for MOHMAT over common period 1970-2006) Berry, D.I. and E.C. Kent, 2009: A New Air-Sea Interaction Gridded Dataset from ICOADS with Uncertainty Estimates. Bulletin of the American Meteorological Society, 90(5), 645-656 (DOI: 10.1175/2008BAMS2639.1). from Dave Berry, National Oceanographic Centre, University of Southampton
Move the mouse towards the axis of interest until the axis is highlighted. Hold down the shift key and the left mouse button and move the mouse to zoom. Hold down the mouse button and move the mouse to pan.
Note: For each dataset, one value is plotted for each year in the period of record. For datasets with multiple values in one year, an average is calculated for one annual value. Missing annual values are interpolated between non-missing values.
