cirrus cloud as obtained from the lidar measurements. The radiance L m and L s are the measured cloud top and cloud base values. The equivalent height is thus the weighted level which would define the upward radiance of an isothermal layer of the lidar defined effective emittance. On a typical FIRE field experiment day ER-2 observations were. Platt et al. () also detected superthin cirrus with visible and infrared optical depths as low as in Kavieng, Papua, New Guinea, at 3°S in using LIDAR. From near-global observations of optically thin cirrus during the LIDAR In-space Technology Experiment (LITE), Winker and Trepte () found layers of cirrus occurring in thin.
From a total of 12 ER-2 sorties flown as part of the TOGA COARE campaign between 11 January and 21 February , four clear-sky scenes and six cirrus scenes were selected. The majority of rejected MIR scenes were excluded either because of cloudiness (much of the time the ER-2 was over deep convective systems) or because the lidar was not Cited by: We present a Rayleigh-Mie-Raman LIDAR system in operation at Clermont-Ferrand (France) since The system provides continuous vertical tropospheric profiles of aerosols, cirrus optical properties and water vapour mixing ratio. Located in proximity to the high altitude Puy de Dôme station, labelled as the GAW global station PUY since August , it is a useful tool to Cited by: 7.

Get this from a library. ER-2 lidar observations from the October FIRE cirrus experiment. [J D Spinhirne; D L Hlavka; W D Hart; Goddard Space Flight Center.]. combined coordinated satellite, airborne, and surface observations with modeling studies to investigate the cloud properties and physical processes of the cloud system.
This data set contains cloud top height and ground height calculations from the ER2 Cloud Lidar System (CLS) during the Wisconsin FIRE experiment in October, The 27–28 October FIRE IFO Cirrus Case Study: Cirrus Parameter Relationships Derived from Satellite and Lidar Data Article (PDF Available) in Monthly Weather Review (11) December A description of the ER-2 lidar data characteristics and available products, plus flight times and locations is presented for the FIRE cirrus experiment of October 13 through November 2, Using aircraft in-situ measurements, the microphysics of cirrus clouds observed on 28 Oct.
during FIRE were examined. Results are presented as one component of. 28 Octoberthe case study period. The data pre-sented here also constitute an initial source for devel-oping cirrus bidirectional reflectance models and may be used to help validate the models employed in the 1SCCP algorithm.
Data a. Lidar measurements Lidar backscatter data were taken from four different sources--three surface and one airborne. Remotely sensed scanning radiometer and lidar data on cirrus clouds were obtained during the cirrus FIRE IFO experiment in November from the ER-2 aircraft plat-form.
Data were examined particularly on 2 November for an area in the vicinity of Wausau, Wisconsin where unusual effects were noticed in bispectral histograms from various channels Author: C. Platt, A. Arking. Michigan on Octo Thebreadth of measurementsavailable for this case allows an examination of all three of the areas of concern mentioned above for a single cirrus cloud field.
However, this is clearly not the case, and from the plot we suggest that a haze layer can be seen at about Km above the site, followed by a further layer at 12.
Lidar cloud studies for FIRE and ECLIPS. Regional Experiment (FIRE) Intensive Field Observation (IFO) program. THE OCTOBER FIRE IF(3 CIRRUS CASE STUDY. INTRODUCTION This paper uses a large and comprehensive data set taken by the NOAA C02 Doppler lidar, the NCAR King Air, and rawinsondes on 31 October during the FIRE (First International Regional Experiment) field program which took place in by: 2.
separates cirrus cloud observations into cirrus and thin cirrus on the basis of the observed extinction values from the satellite experiment. Woodbury and McCormick  extended their analysis to cover the time period from February to November and to provide zonally-averaged cirrus cloud cover and a cirrus global by: Preface The following report represents an article that has been accepted for publication in the upcoming special topic issue of The Monthly Weather Review, which deals with the October cirrus cloud case study from the Wisconsin IFO campaign.
Characterization of cirrus clouds over Buenos Aires (°S, °W) using a ground based lidar is presented. The study, carried out for the period –, reveals that cirrus are usually found in the altitude region 8–11 km, with mid-cloud temperatures values varying between −75 °C Cited by: 3.
A third H 2 O DIAL system called Lidar Atmospheric Sensing Experiment (LASE) was developed as a prototype for a space-based H 2 O DIAL system. This system was designed to operate autonomously from a high-altitude ER-2 aircraft, and it uses a Ti:sapphire laser and 1–3 different H 2 O absorption cross-sections.
coincident Landsat 5 overpass on Octo as part of the FIRE Cirrus IFO in the vicinity of Lake Michigan. A comparative study is made to infer microphysical properties of the cirrus cloud field.
Radiances are derived from the image by convolving the ER-2 radiometer's effective field of view along the flight path. COVID Resources.

Data for this study were collected by the instruments mounted on the NCAR King Air and rawinsonde during the First ISCCP (International Satellite Cloud Climatology Project) Regional Experiment (FIRE) on 19 October, The main purpose of this study is to understand the basic concept of evaporative cooling in a dry layer below Cited by: 5.

Heymsﬁeld and Miloshevich, ). Remotely sensed scanning radiometer and lidar data on cirrus clouds were obtained during the cirrus FIRE IFO experiment in November from the ER-2 aircraft plat-form.
A case study of cirrus layers with variable µm reflection properties in the first FIRE experiment, 2 November. High-Altitude LIDAR. Leveraging past DARPA developments in laser-based versions of RADAR—known as LIDAR, short for light detection and ranging—the High-Altitude LIDAR Operations Experiment (HALOE) provided unprecedented access to high-resolution 3-D geospatial data.
