This report presents upper-air climatology for the lower troposphere (below 850 hPa or 1.5 km) for the Schiphol Area of the Flight Information Region of the Netherlands (EHAM-FIR). The climatology is produced under the program Kennis-voor-Klimaatproject Climatology and Climate scenarios for Hotspot Mainport Schiphol, HSMS02 on request of Air Traffic Control the Netherlands (LVNL). Climatology of the upper troposhere, 850 to 150 hPa, is presented in part 1. The climatology below 1.5 km is based on ERA-Interim atmospheric reanalysis, period 1989-2009. As in part 1, the results of ERA-Interim are (in overlapping period) compared with other sources:

. reanalysis of HIRLAM (2003-2005)

. radiosonde soundings from De Bilt (1989-2009)

. Cabauw-observations (1986-2009, break in 1997-2000)

. OWEZ-observations (2005-2009)

ERA-Interim is a state-of-the-art reanalysis-project of the European Centre for Medium Range Weather Forecast ECMWF, HIRLAM is the operational high resolution model of KNMI and Cabauw and OWEZ are meteorological masts in the centre-part of the Netherlands and off-shore near Egmond aan Zee. Results of these comparisons indicate the agreement between the different sources.
