user: What is geomorphometry?

assistant: Geomorphometry, or geomorphometrics, is the science and practice of measuring the characteristics of terrain, the shape of the surface of the Earth, and the effects of this surface form on human and natural geography. It gathers various mathematical, statistical and image processing techniques that can be used to quantify morphological, hydrological, ecological and other aspects of a land surface. Common synonyms for geomorphometry are geomorphological analysis (after geomorphology), terrain morphometry, terrain analysis, and land surface analysis. Geomorphometrics is the discipline based on the computational measures of the geometry, topography and shape of the Earth's horizons, and their temporal change. This is a major component of geographic information systems (GIS) and other software tools for spatial analysis.

In simple terms, geomorphometry aims at extracting (land) surface parameters (morphometric, hydrological, climatic etc.) and objects (watersheds, stream networks, landforms etc.) using input digital land surface model (also known as digital elevation model, DEM) and parameterization software.[Extracted surface parameters and objects can then be used, for example, to improve mapping and modelling of soils, vegetation, land use, geomorphological and geological features and similar.

With the rapid increase of sources of DEMs today (and especially due to the Shuttle Radar Topography Mission and LIDAR-based projects), extraction of land surface parameters is becoming more and more attractive to numerous fields ranging from precision agriculture, soil-landscape modelling, climatic and hydrological applications to urban planning, education and space research. The topography of almost all Earth has been today sampled or scanned, so that DEMs are available at resolutions of 100 m or better at global scale. Land surface parameters are today successfully used for both stochastic and process-based modelling, the only remaining issue being the level of detail and vertical accuracy of the DEM.

user: Why does pollution in Delhi increase during the months of Nov-Dec each year?

assistant: Delhi is the capital of India and one of India's largest city.  It has over 30 million residents and an estimated 100+ million vehicles.  Delhi is surrounded by the agricultural states of Punjab and Haryana.  During the period Sep-Nov, the states of Punjab and Haryana harvest rice they have grown during the summer months.  Post the harvest, in order to prepare the fields for sowing again they burn the left over rice husk and dried plants.  The month of November marks the onset of winter in the north Indian plains and during this time the north westerly winds stop.  The combination of high vehicle number, large scale burning of post harvest leftover and onset of winter with no winds results in the months of Nov-Dec being the most polluted in the year.
