Atmospheric sciences Atmospheric sciences Atmospheric sciences are the study of the Earth's atmosphere, its processes, the effects other systems have on the atmosphere, and the effects of the atmosphere on these other systems. Meteorology includes atmospheric chemistry and atmospheric physics with a major focus on weather forecasting. Climatology is the study of atmospheric changes (both long and short-term) that define average climates and their change over time, due to both natural and anthropogenic climate variability. Aeronomy is the study of the upper layers of the atmosphere, where dissociation and ionization are important. Atmospheric science has been extended to the field of planetary
Long-term care home and community-based long term care (LTC) used "break-even costs" to prevent institutional care. A recent analysis indicates that Americans spent $219.9 billion on long-term care services for the elderly in 2012. Nursing home spending accounts for the majority of long-term care expenditures, but the proportion of home and community based care expenditures has increased over the past 25 years.
