It means Parts Per Million. It is generally used to measure and denote the concentration of chemical in very low quantity. e.g we say the sea water contains 0.5 ppm of pure gold. Or human blood contains 20 ppm of iron oxide.
This unit is used when other units like % and fractions are too big to denote the quantity.
Percent is one part in hundred. So you can now understand what is a part per million.
Answerppm in this context probably means parts per million. This is the concentration of a chemical or element in something like food or drink.
for example 8 milligrams of Mercury in 100 grams of fish would result in a mercury concentration of 0.8 ppm (parts per million)

AnswerPortable Pixmap. This is a common image format used in Unix systems due to the simplicity of the format. The format is as follows:
P6
Where width, height, and maxval are in ASCII decimal for the width, height, and maximum sample value of the image, respectively. The header portion can also include human-readable comments by using the # character followed by a comment. The image data is just a bunch of uncompressed bytes containing the red, green, and blue sample values of each pixel. There are similar formats called Portable Greymap (PGM) and Portable Bitmap (PBM), and they are defined and treated similarly.
There are many tools for transforming and converting files of these types to other formats. Search for Netpbm for more information.

"Hotel" is the full form of the word. It is derived from the French hôtel, from Old French hostel.
Carbon dioxide levels are not decreasing in the atmosphere, in fact, they are increasing. In 1960 levels were 316 ppm. In 1970 levels were 325 ppm. In 1980 levels were 338 ppm. In 1990 levels were 353 ppm. In 2000 levels were 369 ppm. In 2010 levels were 388 ppm. Jan of 2012 levels were 393.09 ppm. As of today we are at 393.68 ppm at Manua Loa.
