Context: Rotterdam is a city in the Netherlands, located in South Holland, within the RhineMeuseScheldt river delta at the North Sea. Its history goes back to 1270 when a dam was constructed in the Rotte river by people settled around it for safety. In 1340 Rotterdam was granted city rights by the Count of Holland and slowly grew into a major logistic and economic centre. Nowadays it is home to Europe's largest port and has a population of 633,471 (city proper), ranking second in the Netherlands. The Greater Rijnmond area is home to approximately 1.4 million people and the Rotterdam The Hague Metropolitan Area makes for the 168th most populous urban area in the world. Rotterdam is part of the yet larger Randstad conurbation with a total population of 7,100,000., Holland is a region and former province on the western coast of the Netherlands. The name "Holland" is also frequently used to informally refer to the whole of the country of the Netherlands. This usage is commonly accepted in other countries, and not entirely uncommon among the Dutch themselves, though some in the Netherlands and particularly in other regions of the country may find it undesirable, misleading or insulting., The North Sea is a marginal sea of the Atlantic Ocean located between Great Britain, Scandinavia, Germany, the Netherlands, Belgium, and France. An epeiric (or "shelf") sea on the European continental shelf, it connects to the ocean through the English Channel in the south and the Norwegian Sea in the north. It is more than long and wide, with an area of around ., Amsterdam is the capital and most populous municipality of the Kingdom of the Netherlands. Its status as the capital is mandated by the Constitution of the Netherlands, although it is not the seat of the government, which is The Hague. Amsterdam has a population of 847,176 within the city proper, 1,343,647 in the urban area, and 2,431,000 in the Amsterdam metropolitan area. The city is located in the province of North Holland in the west of the country. The metropolitan area comprises much of the northern part of the Randstad, one of the larger conurbations in Europe, with a population of approximately 7 million., The Caribbean (or ) is a region that consists of the Caribbean Sea, its islands (some surrounded by the Caribbean Sea and some bordering both the Caribbean Sea and the North Atlantic Ocean) and the surrounding coasts. The region is southeast of the Gulf of Mexico and the North American mainland, east of Central America, and north of South America., The Kingdom of the Netherlands , commonly known as the Netherlands, is a sovereign state and constitutional monarchy with territory in western Europe and in the Caribbean., The Hague (or "<nowiki>'</nowiki>s-Gravenhage" ) is a city located in the western coast of the Netherlands, and the capital city of the province of South Holland., The KNMI - mast Cabauw is a 213 metre high guyed mast for meteorological measurements at Cabauw , the Netherlands . In 1972 at Cabauw ( 06348 ) a 213 m high mast was specifically built for meteorological research to establish relations between the state of the atmospheric boundary layer ( ABL ) , land surface conditions and the general weather situation for all seasons . The Cabauw mast is located in the western part of the Netherlands ( 51.971 ° N , 4.927 ° E ) in a polder 0.7 m below average sealevel . This site was chosen , because it is rather representative for this part of the Netherlands and because only minor landscape developments were planned in this region . Indeed the present surroundings of Cabauw do not differ significantly from those in 1972 . The North Sea is more than 50 km away to the WNW . The nearby region is agricultural , and surface elevation changes are at most a few metres over 20 km. Within 40 km radius there are four major synoptic weather stations , among which is the regular radiosonde station at De Bilt ( 06260 ) , ensuring a permanent supporting mesoscale network . Near the mast , the terrain is open pasture for at least 400 m in all directions , and in the WSW direction for 2 km. Farther away , the landscape is generally very open in the West sector , while the distant East sector is rather rough ( windbreaks , orchards , low houses ) . The distant North and South sectors are mixed landscapes , much pasture and some windbreaks . So the highest mast levels have in all directions a long fetch of landscape roughness which is usefully similar to the roughness observed in the lower surface layer . On the mast itself no undisturbed measurements can be made below 20 m. Auxiliary 20 m masts are installed to the SE and the NW at sufficient distance from the mast foot building . South of the mast is a well - kept observation field for micrometeorological observations , including soil heat flux , soil temperatures and various radiation measurements ; north of the mast is a spare observation field . The soil consists of 0.6 m of river - clay , overlying a thick layer of peat . The water table is about 1 m below the surface , but can be higher during wet periods . The mast is a closed cylinder of 2 m diameter , with an elevator inside . It is guyed at four levels , and carries booms at 20 m intervals in three directions . The 9.4 m booms can be swung up hydraulically , so that instruments at their ends can be handled from an upper balcony ; this swivelling mounting allows much longer booms than the customary sideways - sliding construction . Permanent signal cables in the boom tubes run through the hollow swivel axis , so during boom motion they are only torsion - deformed , a more endurable load than bending . Built around the mast foot is a 200 m2 streamlined building for registration and maintenance purposes . On top of the mast , a compact weather radar was installed in 2007 , measuring precipitation up to a radius of 60 km around the mast ., Belgium , officially the Kingdom of Belgium, is a sovereign state in Western Europe bordered by France, the Netherlands, Germany, Luxembourg, and the North Sea. It is a small, densely populated country which covers an area of and has a population of about 11 million people. Straddling the cultural boundary between Germanic and Latin Europe, Belgium is home to two main linguistic groups: the Dutch-speaking, mostly Flemish community, which constitutes about 59% of the population, and the French-speaking, mostly Walloon population, which comprises 41% of all Belgians. Additionally, there is a small group of German-speakers who live in the East Cantons located around the High Fens area, and bordering Germany., The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a sovereign country in western Europe. Lying off the north-western coast of the European mainland, it includes the island of Great Britain (the name of which is also loosely applied to the whole country), the north-eastern part of the island of Ireland, and many smaller islands. Northern Ireland is the only part of the UK that shares a land border with another sovereign statethe Republic of Ireland. Apart from this land border, the UK is surrounded by the Atlantic Ocean, with the North Sea to its east, the English Channel to its south and the Celtic Sea to its south-south-west, giving it the 12th-longest coastline in the world. The Irish Sea lies between Great Britain and Ireland. With an area of , the UK is the 78th-largest sovereign state in the world and the 11th-largest in Europe. It is also the 21st-most populous country, with an estimated 65.1 million inhabitants. Together, this makes it the fourth most densely populated country in the European Union., The Netherlands  is the main constituent country of the Kingdom of the Netherlands. It is a densely populated country located in Western Europe with three island territories in the Caribbean. The European part of the Netherlands borders Germany to the east, Belgium to the south, and the North Sea to the northwest, sharing maritime borders with Belgium, the United Kingdom, and Germany.

It's surrounded by the municipalities of Utrecht, Montfoort, Lopik, Vianen and Nieuwegein., Germany, officially the Federal Republic of Germany, is a federal parliamentary republic in central-western Europe.
