As part of our project providing derived meteorological products (DMPs) for solar occultation (SO) satellites and other datasets, I've put together a "generic" or "user-defined" (UD) DMP program that, given a file of the geolocation information in a simple, specific format, will make a file for with a subset of DMP products for each point in the input file. The products include PV and scaled PV (sPV), horizontal winds, temperature, potential temperature, horizontal PV and temperature gradients, and vortex edge criteria. (The only things in other DMP files that are not calculated here are line-of-sight gradients, tropopause heights (these because there is no requirement for the set of locations to be a "profile"), and geopotential height (because it seemed at best marginally useful to most people).) There are UD programs to calculate DMPs from the UK Met Office assimilated dataset (formerly known as UKMO, now commonly referred to as MetO) and the NASA GMAO's GEOS-4 dataset. If you have a use for this sort of product, and can provide an ascii file in the format described below, we can provide files giving you these DMPs for each datapoint in there. If you are interested, copy your request, with a brief description of the project you will be using these for, and the input file attached or appended, to Gloria Manney (Gloria.L.Manney@jpl.nasa.gov) AND to William Daffer (William.H.Daffer@jpl.nasa.gov). ------------------------------------------------------------------------------- Input file format: ------------------ Exactly one header line with anything you want; then lines for each location with: year(i4) day-of-month(i2) month(i2) time(sec, i5) lat(deg) long(0 to 360 or -180 to 180) alt(km) pressure(hPa) fields separated by space and/or tab), e.g.: -------------------------------------------------------------------------------- year dayOfMonth month time_sec lat long alt_km press_mb 1992 14 9 69120 35.95157 -107.2847 45 1.5472 1992 14 9 73393 35.71619 -106.76519 44 1.758 1992 14 9 77416 35.4982 -106.24747 43 2.0002 1992 14 9 81093 35.30545 -105.80916 42 2.2798 1992 14 9 84401 35.14108 -105.5408 41 2.602 1992 15 9 1046 35.00023 -105.50462 40 2.9759 1992 15 9 3361 34.91613 -105.96932 39 3.4167 1992 15 9 4231 34.93019 -107.03894 38 3.9284 1992 15 9 4349 34.96019 -107.62753 37 4.5191 1992 15 9 4481 34.98525 -108.12088 36 5.2051 1992 15 9 4563 35.00581 -108.46029 35 6.0015 1992 15 9 4633 35.02474 -108.74819 34 6.9286 1992 15 9 4703 35.04383 -109.0409 33 8.0047 1992 15 9 4763 35.06085 -109.28864 32 9.254 1992 15 9 4815 35.07641 -109.5044 31 10.71 1992 15 9 4868 35.09212 -109.72345 30 12.412 1992 15 9 4920 35.10783 -109.9425 29 14.408 1992 15 9 4969 35.12268 -110.14435 28 16.729 1992 15 9 5013 35.1366 -110.32772 27 19.434 1992 15 9 45929 35.21105 -104.58245 26 22.535 1992 15 9 45970 35.19699 -104.75397 27 19.363 1992 15 9 46015 35.18265 -104.93924 28 16.648 1992 15 9 46061 35.16817 -105.13033 29 14.317 1992 15 9 46107 35.1537 -105.32152 30 12.331 1992 15 9 46163 35.13788 -105.55042 31 10.639 1992 15 9 46215 35.12253 -105.76618 32 9.1841 1992 15 9 46266 35.10727 -105.98003 33 7.9398 1992 15 9 46324 35.09089 -106.21928 34 6.8698 1992 15 9 46392 35.07264 -106.50089 35 5.9508 1992 15 9 46460 35.05442 -106.78153 36 5.1635 1992 15 9 46532 35.03565 -107.07983 37 4.4887 1992 15 9 46638 35.01297 -107.5058 38 3.9091 1992 15 9 46699 34.98908 -107.90766 39 3.4065 1992 15 9 47102 34.9597 -108.76902 40 2.9719 1992 15 9 48538 34.98991 -109.53211 41 2.597 1992 15 9 51315 35.1043 -109.93506 42 2.2717 1992 15 9 54473 35.23731 -110.17836 43 1.989 1992 15 9 58142 35.38596 -110.36925 44 1.7438 1992 15 9 62421 35.5484 -110.58237 45 1.531 1992 15 9 67274 35.72149 -110.8536 46 1.3446 1992 15 9 72538 35.90106 -111.18092 47 1.1804 1993 3 4 73381 36.53885 -118.64266 44 1.7327 1993 3 4 76108 36.19093 -117.2206 43 1.9758 1993 3 4 78873 35.84009 -115.79476 42 2.2565 1993 3 4 81673 35.49008 -114.40012 41 2.5797 Output format (one file for all locations In the input file:) ---------------------------------------------------------------------------------------- Met Office Derived Meteorological Products year mon day time lat lon alt press MetO-theta MetO-T delh-T Zon-Wind Mer-Wind PV sPV EqL delh-PV EqL-edge EqL-inner EqL-outer 1992 9 14 69120 35.95 252.72 45.00 1.55 0.1645E+04 0.2589E+03 0.1575E-02 -0.9728E+01-0.5998E+01 0.2469E+02 0.6032E+00 0.3472E+02 0.1365E+01 -0.1778E+02 -0.2278E+02 -0.1778E+02 1992 9 14 73393 35.72 253.23 44.00 1.76 0.1576E+04 0.2572E+03 0.1714E-02 -0.8806E+01-0.5630E+01 0.2248E+02 0.6572E+00 0.3567E+02 0.1480E+01 -0.1683E+02 -0.1933E+02 -0.1683E+02 1992 9 14 77416 35.50 253.75 43.00 2.00 0.1508E+04 0.2555E+03 0.2675E-02 -0.8087E+01-0.5261E+01 0.2021E+02 0.7092E+00 0.3668E+02 0.1554E+01 -0.1582E+02 -0.1832E+02 -0.1582E+02 1992 9 14 81093 35.31 254.19 42.00 2.28 0.1442E+04 0.2536E+03 0.2905E-02 -0.7170E+01-0.5074E+01 0.1756E+02 0.7429E+00 0.3741E+02 0.1585E+01 -0.1509E+02 -0.1759E+02 -0.1509E+02 1992 9 14 84401 35.14 254.46 41.00 2.60 0.1379E+04 0.2518E+03 0.2226E-02 -0.5941E+01-0.5202E+01 0.1454E+02 0.7415E+00 0.3634E+02 0.1578E+01 -0.1616E+02 -0.1866E+02 -0.1616E+02 .....
