   >>>>>>> Next I will comment of accuracy and precision of gun.   
      
   Now is the time to comment on accuracy and precision of the gun. First I   
   pointed the laser at my forehead and got a reading 3 C. below a mouth   
   thermometer reading. Then I realized that I did not have a fever. Such a gun   
   is used in medical science so it can be trusted as a scientific instrument.   
   It gives a varying number significant figures and I try to take multiple   
   readings when needed.   
      
   There is a button to turn off the laser. When off, reading are not Raman   
   thermometry. 35 years ago I published on combustion in Proceeding of  the   
   American Society of Mechanical Engineers and the ASME has agreed to publish   
   a new version. So I can presume I am an authority on combustion.   
      
   I have a BIC lighter and the flame is blue at the bottom and yellow on top.   
   There are carbon black particles in the yellow flame so it can be assumed to   
   be  black body radiator. The red laser measures the temperature of a surface   
   by Raman scattering. I shone the laser at the flame and it went right   
   through, no surface. The gun reading was 5C. above ambient. I estimate that   
   a thermocouple temperature reading would be ~500 C. depending on location.   
      
   In laboratory IR spectroscopy, fused alkali halide windows are used NaCl,   
   NaBr. KCl, KBr. The gun has some kind of plastic Fresnel lens. I need to   
   consult the patent to learn more.   
      
   I child might contour the comfortable zone around the flame Hot air rises so   
   one cannot place a hand even six inches above the flame. In the horizontal   
   place a finger tip can be brought within 0.5 cm. This is "Greenhouse". It   
   demonstrates the Beer-Lambert Law, extinction coefficient and extinction   
   depth. Tarmac is a perfect black-body. The heating zone is that thin   
   reflective mirage you see on a hot sunny day. "Greenhouse" is near your   
   ankles not above your head.   
      
   IR Raman does not work with a flame. IR thermometry does not work either   
   because of the short extinction depth. The IR Raman gun is made of plastic.   
   If it goes too close to the flame it will melt.   
      
   Radiation of cold appears to be contrary to radiation of heat. Heat energy   
   flows downhill. One can take the IR Raman temperature of low hanging cloud   
   because heat energy flows out of the gun upwards. Remember thermal inertia.   
   This takes time and one repeats until a meaningful reading is found. Only   
   temperatures below zero are meaningful. IR Raman and IR readings need not be   
   the same because they use different physics.   
      
   For generality it might be useful to build a station at 600 meters. Use a   
   concrete slab for the ground. Protect that slab from Sun and wind on three   
   sides so it radiates into the North. Only note the lowest temperature and   
   that might warn of killer frosts. Make this under computer automation,   
   telemetry. One does not want too much data only that which is meaningful. A   
   second gun would be directed up towards to North West sky to capture the   
   coldest reading. This may correlate with Thermosphere Climate Index, which   
   is a satellite reading from above.   
      
   Elsewhere I showed that the weak IR absorption of CO2 overlaps with the IR   
   band for water. Water is the great IR absorber, but "Greenhouse" is near   
   your ankles. H2O is bent and has a permanent dipole moment. Einstein showed   
   that what absorbs also emits. But CO2 is a piss poor absorber and so for its   
   emissions. One cannot measure CO2 emissions from a satellite. Instead a   
   polar molecule is used instead. NO nitric oxide has a nice permanent dipole   
   because of the electronegativity difference between nitrogen and oxygen   
   atoms. Nitric oxide can be formed by photodissociation, as with ozone O3.   
      
   It would be nice to get collaboration of satellite reading with land based   
   readings.
