Two new data set have been released by the NASA Socioeconomic Data and 
Applications Center (SEDAC <http://sedac.ciesin.columbia.edu/>) operated 
by CIESIN <http://ciesin.columbia.edu/>:

The India Village-Level Geospatial Socio-Economic Data Set, v1 (1991, 
2001) 
<http://sedac.ciesin.columbia.edu/data/set/india-india-village-level-geospatial-socio-econ-1991-2001>, 
provides detailed administrative boundary data for India 
(village/town-level) together with more than 200 socioeconomic variables 
from the 1991 and 2001 censuses. The data are available for the 28 
states and combined Union Territories in existence in 1991 and 2001. The 
data set was developed as part of a research project on the dynamics and 
determinants of land change in India by Prasanth Meiyappan of the 
University of Illinois and colleagues from India and from Columbia 
University. This is the second data set in the India Data Collection 
<http://sedac.ciesin.columbia.edu/data/collection/india>, which also 
includes the data set, India Annual Winter Cropped Area, v1 (2001–2016).

SEDAC has also released a new data set on global patterns of fine 
particulate matter (PM_2.5 ) over nearly two decades: the Global PM_2.5 
Grids from MODIS, MISR and SeaWiFS Aerosol Optical Depth (AOD) with 
Geographically Weighted Regression (GWR),  v1 (1998–2016) 
<http://sedac.ciesin.columbia.edu/data/set/sdei-global-annual-gwr-pm2-5-modis-misr-seawifs-aod>. 
The data set consists of estimated annual concentrations (micrograms per 
cubic meter) of PM_2.5 , with dust and sea salt removed, on a grid of 
0.01 degree resolution, or about 1 km at the equator. This 
version supersedes a previous data set with coarser resolution (0.1 
degree, or about 10 km) and data only through 2012. The new data set 
combines AOD measurements from the NASA Moderate Resolution Imaging 
Spectroradiometer (MODIS), Multi-angle Imaging SpectroRadiometer (MISR), 
and the Sea-Viewing Wide Field-of-View Sensor (SeaWiFS) with a chemical 
transport model. GWR is used to adjust estimates drawing on available 
ground-based measurements. The data set was developed by a team led by 
Aaron van Donkelaar at Dalhousie University in Canada.
