This data set includes meteorological, soil, permafrost data obtained from the long term observational site Samoylov, located in the Lena River Delta, Siberia, between 1998 to 2018. The instrumentation, calibration, proccessing and data quality control is explained in Boike et al. (2018).The mean annual air temperature 1998–2017 was calculated as -12.3 °C, but includes years with missing data (1998, 2000–2003, 2005, 2006, 2009, 2010). Including only years with full data records (1999, 2004, 2007-2017), the mean annual air temperature is -11.7 °C. Similarly, the mean monthly temperatures of the warmest month (July) is computed as 9.4 °C (average of years 1999, 2004, 2005, 2007, 2008, 2011-2017) and for the coldest month (February) -31.7 °C (average of months of 1999, 2000, 2004, 2005, 2007, 2008, 2011-2017). The average summer rainfall (June-October) was 145.2 mm (average of years 1999, 2003–2008, 2011-2017).
